So I've decided that "the Phantom Pain" is definitely for the Vita. We all know that it's the new Metal Gear, I just want to talk about why it's a Vita game.
Here's some supporting evidence:
1. these screens are 960 × 540. the Vita’s is 960 × 544.
2. The trailer is lacking details in the environment and in some action sequences i can see things like hair sort of "pixelate" out. I’ve seen the same thing in Uncharted GA. Also some really bad aliasing that is not seen in the Ground zeroes trailer. Basically everything is lower in quality to the GZ trailer.
3. a metal gear game has never used roman numerals. this could mean that "V" actually means "Vita", not "5".
I’m convinced that this game is a Vita tie-in to Ground Zeroes. the GZ trailer mentions "Two Phantoms" and Kojima would have a helluva time with the quirks Transfarring could have.
