The article you posted is incorrect. Avatar uses the dunia tech 3d engine:

It is either rendered at 640x720 or 1280x360, exactly one half 720p image for each eye. HDMI 1.2 does not have the bandwidth for full 720p each eye.

It's only the PS3 that is capable of 720p per eye. That is the definition of the HDMI 1.4 full 720p/60 3d standard. And this is one of the modes that the new tv's take. It is not capable of higher then that for games. They didn't even bother letting developers have access to the full 1080p/24 mode, they reserved it for movies.

Im not saying the PS3 can realistically render call of duty higher then 640x720 or 1280x360 per eye, which would be the maximum on the 360.

Well, I was proven wrong for Avatar...lol. Avatar was 720p after all cut in half...I thought it was 1080p/2.

But I am 100% sure about HDMI 1.2 spec. It definetly has enough bandwidth for pushing 1080p, hence it can do 720 per eye.

Doing 720p per eye takes less bandwidth than doing 1080p and there are multiple 360 games which do native 1080p resolution. Also, HDMI 1.2 cables 3.96 Gbits throughput which supports a maximum of 1920x1200@24bit. That is a lot more bandwith than 720p per eye in 3D needs.

Avatar was most likely 720p/2 per eye as Ubisoft couldn't get it to run at a higher resolution on either systems.

PS3 HDMI port is 1.3 and has more badnwidth 10.2 Gbts vs 3.96...and theoretically can push 1080p per eye 3D but that won't happen as PS3 can't do it and TVs cant accept it.

Awsome, I can use my Michael Jackson 3D glasses again!

Ya we were both wrong. HDMI 1.2 definitly has the bandwidth for full 720p 3d, just not full 1080p 3d. The HDMI 1.4 TV's do accept the full 1080p 3d format though, just only at 24fps, the PS3 uses it for blu ray movies, but it's not realistic for games.

The reason some think higher then half 720p wont be done on the 360 is not because of bandwidth but because the frame won't fit in the 10mb EDRAM. That limitation hasn't stopped developers before though, sacrifices just have to be made.
