The PS3 might do 2xAA, but it won't be free, so it'll have to either lower its graphical features or not use it.

Why wouldn't the PS3 have any AA? I actually think that none of the Ps3's games have any noticible aliasing in any decent launch game.
The PS3 games aren't too impressive from a graphics standpoint. In some things, it looks great, but others look too bland.
yeah i'd think 1080p is definately out the question if AA is required or used....probably not enough memory and definately not enough bandwidth on the 128bit wide bus.
the 360, actually cant provide any AA for free on a full 720p image..... the 10mb edram just isnt enough
but they get around this by employing a tile based renderin system, that uses large tiles (to minimise the amount of geometry/data that has to be worked on twice or more) but small enough to easily fit into the 10mb of ram to get the "hit-less" AA
Ati reckoned on 2xAA being pretty much free, and 4xAA (using the same system) to be about 95% the performance of 2xAA.
i guess what really helps is everything about the R500 has been designed to work optimally at the 4xMSAA level. it wasnt make a GPU and oh right lets add AA support. its been in there right from the start as a requirement
theres a seriously good article on the Xenos GPU on beyond3D. if you jus go to their site you will see it in the top right corner
but in fairness, @1080p unless its BF2 (which seems to need AA at any res) then AA shouldnt really be necessary. AF will be much more important.... an i just hope the inferior AF (shimmering etc) of the G70 gpu hasnt filtered over to the RSX for which it is a base
