Just to clearify, by "all games", I meant major titles, as I, and the BB guy was not at all concerned with the resolution of XBL arcade games.
Now, it seems accepted knowledge now that virtually all major titles for the 360 are 720p native. By connecting via HDMI, you have the option of having the native 720p upscaled to 1080p. Is this agreed upon?
The question now is: Is there any benefit to this?
How significant is the difference between 720p upscaled to 1080p and true native 1080p, and is upscaled 1080p any better than native 720p?
Also, I have read several game reviews comparing different versions of games, mostly at gamespot, and usually the reviewers see no difference in quality between the 360 and ps3 versions, even when the ps3 version is native 1080p and the 360 version only upscaled.
Also, on a more personal note. I previously upgraded from component connection to HDMI on my 360, and did notice a SLIGHT in game improvement on every game I tried. But weither or not the improvement was due to increased resolution I am not sure.
