I leave it up to you on how to defend that best; all I want to hear an actual explanation beyond the obvious. Maybe thats too much to ask...
OK, I will do my best, especially considering you pollute other threads with demanding an explanation from me.
Based on developer discussions, it seems that currently developers have already been tapping well over 90% of the XBox 360's performance resources. That's why I don't think it will be possible for the XBox 360 to run games like BioShock, Gears of War or Halo 3 in 1080p.
The amount of additional resources needed to run a game with the same effects in 1080p instead of 720p is estimated to be about 60-100%. Current 720p games on the PS3 are only estimated to be scratching the surface of what is actually possible with a fully SPE enabled / well optimised game engine, well below 40% of the console's game performance potential.
