Monthly sales don't matter in the long term.. what matters is, as a dev/publisher you can say "well if i develop x game now, when its released in x months time will the installbase be big enough to guarantee returns?" - in this case the answer is already "yes" for the 360 in most cases with the PS3 soon to be yes by this time next year without question (& I doubt any games early on in development this yr will see release before that time..)
That's just bogus..
I agree that there's definitely going to be at least one AAA title which doesn't rack up the sales it deserves (or maybe it needs to break even) however i'm pretty sure this has more to do with market saturation than size of the install base since this kind of thing happened on the PS2 even upto the end of it's life.. At the end of the day if your trying to launch a FPS this fall against Halo 3 then I don't care how big the install base is, your game is going to sell like ass unless its already an established franchise (but even so your sales would still be affected)..
In what respect is this happening with the 360 and DS?
DS support grew as a natural progression.. 360 support has been strong from the onset?
And lastly i'm not sure whether you can even infer that Wii gamers on the aggregate are "craving" AAA titles when so far its the mediocre ones that have sold very well generally (in terms of grosse ratio of cost : return).. Zelda sold badly in Japan and even though overall it sold quite well, this still hasn't prompted third parties to invest more money per game in Wii titles (see the nintendo dominate mentality i mentioned earlier).. The vast majority of Wii gamers also are casuals and thus probably care as much about AAAs as they do most of the shallowware thats been released so far.. Someone around here once said "they are just looking for something to play.." and its so true..
You keep quoting sales figures as if it matters when it doesn't.. Sure it means more games will go the way of the Wii but this sure as hell doesn't mean that it will take away from the HD consoles in terms of the capacity and investment going into development, I can assure you..
MS and Sony didn't market themselves towars the casuals from the onset.. They marketted themselves towards the hardcore.. For MS its paid off and the market is only waiting for a price cut (however small) and sales should start to race forwards again.. The PS3 priced itself a little too high but with a recent price cut and more on the way it's pretty clear that the platform is slowly and surely establishing it's foothold as financially viable platform.. Added to that the benefits of cross-platform development and it's pretty hard to write them off as platforms you can't make money off unless you plan on releasing Wii Sports..
Don't we all.. At the end of the day the prices will come down and no matter how fast the Wii is picking up the casuals, it's not going to stop gamers who love their Halos, Metal Gears, Final Fantasys, Gran Tourismos and Mass Effects, picking up one of Sony's or MS's new shiny toys..
The age of the single market is fading and the concept of "console market share" is becoming more and more irrelevant (due to overlap and console diversification dramatically increasing market growth.. more than anything else) in the grand scheme of things..
So as a 360 owner you really have nothing to worry about..
