odd xbox 360 requirements?

I was reading some of the xbox 360 requirements and the things I think are:

- all games require HDTV support
- all games require at least 2 times anti-aliasing

Won't Neo Geo ports etc (I am assuming they will continue with the trend of porting older games) and ports of other 80s/90s games to the 360 look blurry with the Anti Aliasing? Also, isn't it a waste of memory/processing power (which obviously will be in abundance) to display something like an Atari 2600 graphic (perhaps usually represented by a small number of pixesl) as a series of several thousand repeated pixels? Other than possible blurryness of Neo Geo games being Anti Aliased, how can such a requirement be a good thing?

I think those specs are for games that actually "need" it.
I don't think they will use anti-aliasing on 2D games, they aren't supposed to have it and don't look any better with it either.

Interesting....I'm really not planning on getting the 360 anytime soon though, since I really would prefer a consolized supergun for Christmas this year.
