the AA that we are seeing in Xbox360 games that use it, is what I had expected from last generation, PS2,GC,Xbox and even Dreamcast. but most games completely lacked any real anti-aliasing last gen. true, some had AA but most did not. alot of games used what's called flicker filter, a technology that I don't understand very well--but anyway, if you go back to before last-gen, and look at the highend arcade scene with MODEL 3 dominating in technology, you see most if not every MODEL 3 game had some amount of AA. I recently watched Scud Race very carefully. while you can see some aliasing, its not the raw jagged type, because some AA is clearly applied, which is not the case with most Dreamcast, NAOMI, PS2,System 246, NAOMI 2, Gamecube, TriForce, Xbox, and Chihiro games.
as for the next console generation: Xbox720, Wii2, PS4 (or at least the X720 and PS4) I expect very low cost, almost free 16x anti-aliasing. that's the level of AA that makes the jaggies really disappear. although decent prerendered CGI in cutscenes, techdemos, television, etc. no doubt use a significantly higher amount of AA.
on the highend realtime side, with 4 or 8 Nvidia GPUs, I think they're upto 32x AA if I'm not mistaken.
as for Hollywood and Wii anti-aliasing, I don't expect much, maybe games will use more of what Gamecube already had, but didn't use because of fillrate restrictions. Wii has at least a wee bit more fillrate so, 2x or 3x AA should be used more often. I forget the level of AA that Gamecube was capable of, I think it was 3x max.
