It's CryEngine, the PS4 could handle it easily. Just looks RAM intensive, which would be no problem, obviously.
However, the developer is doing this without a publisher and doesn't seem to want one. "Star Citizen is a PC game through and through and could never be played on the Xbox 360, Playstation 3 or WiiU." I would guess they're not just talking about the specs but also that the game is designed for KB/M.
That being said, Sony has never been adverse to taking PC games and publishing them on Playstation only, with only a console-specific exclusive clause. Besides that, they can self-publish, as with The Witness. They've said certification will be a lot more developer friendly with the PS4.
Still, it's obvious that PC development is the focus here. I don't think we'd see a console version for a long time, if ever.
