The Radeon 7670 isn't even a 50% improvement in fill rate over the PS3.
RAM is the hard limit on the amount of content you can put on screen. Most games last gen were designed for the PS2, which had 32 MB of main memory. This gen, we've gotten a 16x increase. If we're talking a 4x increase in RAM for next gen, that's more like Dreamcast to Xbox than PS2 to PS3. Noticeable, sure, but not going to set the market on fire. We're not talking going from MGS3 to MGS4, we're talking about going from current-gen Crysis 2 to PC Crysis 2 at best. I mean once you've gone from the all-to-frequent 600p to 1080p, improved the texture resolution and mesh fidelity, and increased the LOD, how much more memory are you really going to have to put anything interesting in there content-wise?
Sure, Battlefield 3 on a next-gen console with 2 to 4 GB of RAM will have the full maps, but the difference between "64 player Battlefield 3 with fancier shaders" and "24 player Battlefield 3 with not quite as fancy shaders" isn't anything like "Call of Duty: Big Red One vs Call of Duty 2."
They'd better have more up their sleeve than a modest hardware upgrade. Heck, the only reason I went with the HD consoles this gen is the software library on the Wii was so abysmally bad. Nintendo very nearly sold me one of the things.
