liolio:
I generally agree with you about what Nintendo should do.
My comments about what Nintendo is going to do are based solely on the information we've been gathering regarding its final performance.
I tend to speculate keeping in mind the most legit information we have:
Especially the "unparalleled next gen perf", so while supposedly not qualifying as "real next gen" (such a mess of a naming...) I expect it to be really consistantly above the ps360.
A 640-shader, 32 TMU and 16 ROP RV740, plus an UMA of 2GB 128-bit GDDR5 would put the Nintendo Stream with 3->4x greater graphics capabilities than the PS3 and X360 and clearly allowing a disruptive difference in its games' visual quality -> even if they just copied the 163 million transistors Xenon.
I read again reviews of the HD 4770 and it's too big of chip for what N seems to aim at. Something I don't agree is your 3->4x improvement vs the ps360, the hd 4770 is imho more than that, taking FLOPS alone it's already 4x times xenos perfs, but it says a only tiny part of the story as the chip makes much more efficient use of its resources, then texture units have nothing to do with ps360 ones, RBEs does a much better job out of the availlable bandwidth than RSX ROPs and so on. Clearly if devs were to go a bit closer to the metal they could extra a lot more out of it. Anyway it's too much of a chip anyway.
On the other hand something close to Llano/ HD 4670 (Llano has more unit clocked lower) could imho provide a meaty 3->4x jump in perfs over the PS360 not in something as obvious at framerate at a given resolution, but taking in account the quality of shading/effects, AF, etc.
Having the GPU some cyle away from the CPU could also help as I remember reading how communication latency between Xenon and Xenos prevent some devs using the memexport more often (synchronization issues, etC.).
With all the rumours converging to a console that will simply "match" the current crop, everything points that Nintendo isn't aiming at that level of performance. They just want to show off the new gimmick (controller) and at the same time regain support from decent 3rd parties.
You may be right but I tend to think the N could surprise people a bit in this regard, cause they have to (as we agree on what they should do). N won't survive an hardware gamecube like sales (I know the GC made money but they would lose so much mind share, third party supports, etc.).
What I consider "worse it" out of the rumours we had (as so many sites are after clicks...) is a POWERPC 3 cores CPU, a R7xx based GPU, 8GB of flash storage and BRD disk/player. See what happen this gen, most site don't have a clue, they don't get FLOPS even simple thing as resolution (if they get it they don't care "clicks FTW...). I would not be surprised reports are simply based on resolution aimed by N for rendering either it's 1080p or 720p (actually rendering @1080p is already twice the processing/bandwidth requirements).
Let's not forget that Nintendo has always had a steady 5-year longevity for their home consoles.
With the PS4\X720 launching on 2014 with "exquisite" hardware, it'll take at least until late 2015/2016 for the developers to really come up with "disruptive-looking" games, and that's only a year away from Nintendo launching the successor to Stream, with a new gimmick and hardware that matches the other two (at a fraction of their initial price).
So it makes even more sense for N to make its system reasonnably attractive to gamers. I want to upgrade my pc but I no longer want PC (I may get a tablet as I realize that I don't need windows/linux I simply don't do much with my PC), my wife would happily welcome a N console (for mario kart and some other mario game she likes) my-self a Llano grade hardware along with the possiblity to play on the pad (quiet convenient concept if done right imho) may fell my need for some years (espceially if Diablo ii comes on the system
).
Of course, none of this prevents them to invest heavily in a new and up-to-date network environment, as that is equally crucial to keep up with PS3 and X360.
They will have too, I wonder if after the PSN debacle an Valve /Steam offer would be even more tempting for N as it could allow them to catch-up faster with MS/Sony.
