Will Fox Engine make for scalable cross-gen Metal Gear games?

Everyone present went "ooh" and "aah" at the Metal Gear 25th anniversary event, as Hideo Kojima showed off the Fox Engine-powered Metal Gear Ground Zeroes. No shots have leaked out of worth, but the likelihood is that Fox Engine can power both this and next generation games, much like Square's Luminous Engine, the new Unreal Engine 4 and so on.

That scalability should also enable future games developed on it to hit the Vita, and there's every reason to think that Kojima's next-gen babies will head our way, as he has put so much into the PSP and Vita so far. It is a shame that Revengeance can't make it across, but that non-Konami engine is clearly less scalable, doing things the Vita can't hope to pull off.
