Well, since you are the one who made the "plenty of PSP games past 1 million" quote in the 1st place, why don't you provide your own set of (hopefully more reliable) data to prove your point ? I provided a link, with which you disagree (btw, the Wikipedia entry provided by Darkblu is currently locked because of controversy and inaccuracies). Yes, all we have are estimations. But those estimations are at least extrapolated from actual data. You can argue about the details of said extrapolation, but before that either show us your own data on those many under the radar PSP Platinum games, or explain us how 4 games (giving you Wipeout) constitute "plenty".
Well, it's just that the info on how well the games sold isn't very readily available, that's the problem. There's really not much reliable data, except from publishers themselves. I got the Wipeout figure by accident on some business/turnover related webarticle that just mentioned it in passing. I can't even remember it, but it did mention a few others. I remember having thought that only DS games had broken the 1 million mark, mostly thinking this myself because there's often just Japanese figures available (which have been invariably impressive).
While searching for the link again, I did come across a link that indicated that the DS shipping figures had been overstated, and that DS sold meant sold to shops, not to customers. But it was an article for which you have to pay, and I don't want to go through the whole registration process right now (maybe later), so let's ignore that for now.
I also came across this one, but I do remember that NPD figures are considered unreliable by some. Still, it just goes to show that it's hard to work with reliable numbers, as these NPD figures are still a lot more than we have on Europe. More importantly, you used the NPD figures, and if you consider them reliable, then also consider this:

HARDWARE
August
DS Lite: 250,599 / DS: 27,503 = 278,102 (5,869,374)
PSP: 146,893 (5,003,534)
SOFTWARE
August
DS: 1,090,810 (18,337,100)
PSP: 875,638 (16,880,290)
Difference: 215,172 (1,456,10)
What this clearly indicates is that regardless of the totals, unless in Europe the difference between the DS and the PSP is huge, the difference between the DS and the PSP overall must be largely defined in Japan, and we know the figures for Japan. If all that is the case, then I don't believe that the DS reached 20 million when Nintendo claimed it did either. Do you? At the very least we'll have to conclude that either NPD is low, or Nintendo is high.
And what better way is there to keep perspective than calling 4 games "plenty" ? After all, actual handheld sales figures have a well-known Nintendo-bias, so some matter of "balance" is needed.
Well, I originally thought only GTA did that well, but as I said, I discovered my mistake. Now it is apparently 4 on PSP against 10 on DS, though still based on limited data (Kudos on Nintendo for having relatively good data management). But ok, plenty is far to relative a term in this case anyway. Suffice to say that the PSP has 4, and the DS has 10.
Thanks for the link on better revenue per unit for the PSP, I remember this conversation. Revenue per unit is a bit of a misleading notion, though, since it doesn't take into account development costs and actual sales.
Agreed. But if we look at the NPD figures, then it's not hard to imagine that the PSP sells sufficiently to make a decent profit. Sure, the PSP may have higher development costs in some cases, but not in all. The DS isn't that easy to program on if you want to achieve something special and it is interesting to see that of the 10 games with over 1 million sold, nine are Nintendo. For multi-platform developers, developing for the PSP may actually be cheaper because they can reuse a lot of things for a lot of their titles, which could make PSP games very cheap.
Hey, but the whole discussion came down to whether or not the PSP is a failing system, and the answer should definitely be "not likely". Sure enough right now the DS is doing better, but the PSP is still going strong and there is a long line of excellent games coming out. Even if the PSP hasn't made it quite beyond the 20 million mark just yet, both systems have now reached a price that will allow them to sell really well over the holiday season and by late next year, both systems will definitely be platforms large enough to stay.
Remember, the PSP is a huge number of games in the following months including several heavy hitteres. Just to name a few: MGS, FF, PES6, FIFA07, Lumines 2, Virtua Tennis 3, Lego Starwards II, Socom Fireteam Bravo 2, GTA: Vice City Stories, Ace Combat, Killzone: Liberation (just read the first review in Dutch, looking good), Madden 07, The Getaway, Medal of Honor: Heroes (with 32 player multiplayer), Championship Manager 2007 and Football Manager Handheld 2007, Marvel Ultimate Alliance, Prince of Persia: Rival Swords, Tony Hawk Project 8, Mortal Combat: Unchained, Toca Race Driver 3, Thrillville, etc. etc. etc.
Add to that the updates still coming, with the PSOne emulator, the E-Distribution network that should be great for small 'homebrew like' applications, tools, and probably more original games as it will lower the financial threshold for them, demos, trailers, downloadable movies, tv series, and what not for the PSP, the GPS and Eyetoy, and then when the PS3 is finally released there will definitely also be some extra interest for people to get a PSP for the extra features and so on.
In short, the future looks good to me.
