Sure it could. The graphics would just have to be scaled down quite a bit.

Honestly though the main COD audience is going to pay $60 for the console version to play on their big screen TV. They're not going to pay another $40 for the same game on a 5 inch display.

What game was that? Was it a CoD? I seem to remember that claim being made around CoD4 time, I think (about a game being ported to the Wii)

It was Resident Evil 5

it can run but why would anyone choose Blops 3 on vita instead of Ps3 or 360 ? makes no sense.

It could but it would be pointless thanks to the Vita's lousy battery life and their aren't enough wifi hotspots to actually play it on the go online. Since the 3G version is useless for online play.

Will be interesting to see how well Resistance runs on the Vita, what FPS it gets etc. I'd imagine Nihilistic will be getting a lot of help from Sony to make it run smoothly, so we'll have to see.

exactly

Oops I guess there is a Call of Duty coming out for Vita this year. I didn't think there was one but there's so many gaming websites reporting that there is and even a comment from a Sony exec so it must be happening.

But Golden Abyss does run at a 3rd of the resolution (720x408) with no AA, lacks animation blending (a highly demanding feature which has always been a crown jewl in the Uncharted games' tech), has lower res shadows and alpha effects, lower res textures and less detailed models. And yet still dips to the low 20s in framerate.

Considering that COD already runs at 960x544 and has low res textures etc there is much less room to lower other things to maintain the framerate, especially as a COD port is likely going to get far less attention than an exclusive 1st party game. a resolution of arround 720x408 + a rock solid 30fps would be a great achivement for the Vita.
