I'm not sure just how many 1080p first party titles we'll see on the Xbox One. The leaker claimed that both Forza Horizon 2 and Halo 2 Anniversary will be 1080p. Other than those though, it's hard to tell. Quantum Break looks likely to be 900p considering how good it's graphics are. Sunset Overdrive could be 1080p since they seem to be going for a cartoony cell-shaded art style, but then again they might op for 60 fps instead. An older leak said that only the weapon and hud in Halo 5 would be 1080p, the 2nd pane would be 1920 x 720.

Yeah, I think most 1st party titles will be at least 900p, especially once the SDK is updated. Personally I'm perfectly ok with 900p, I'd rather see a gorgeous game in 900p, like Ryse, than one that barely looks better than last-gen running at 1080p. Some people are just making way too big a deal about resolution, in my opinion framerate, textures, anti-aliasing, physics effects, etc are all more important than 1080p.

Lolll, Dw it ends on Wednesday =P You have plenty of time to get a few more games in, not playing much might make you more excited to play the full release =P it's only a month away

They're supposedly working on adding digital preorders, but there's no guarantee that they'll be ready in time for Titanfall.
