Ground Zeroes will probably end up PS3/360 (low res, crappy graphics version) and 720/PS4 (the actual "how the developers intended it to be played" version). There's no way IMO looking at that trailer that the game isn't running a fairly high end PC rig right now.
They're not allowed to announce a PS4/720 version yet because those platforms don't "officially" exist, not at least until after this holiday season when Sony/MS are done milking one more year out of their old platforms.
