Halo 2 might not hit 1080p - guiz we need to talk about this

[Barozi]

Has probably been said enough already.
Halo Anniversary, 3 and 4 are just straight 360 ports that, due to more power on X1, run at 1080p 60FPS without problems.
Halo 2 Anniversary is being built from the ground up for X1 and thus won't stop at 360 graphic levels. On top of that, like Combat Evolved Anniversary it has two engines running at the same time (which is a great feature IMO) and thus won't come close to whatever Halo 5 will offer.
