I'd say that WWHD would sell more vs. TLOUR on normalized curve where the "population" between the two system is taken into account. This is because WW to WWHD is a generation gap, TLOU to TLOUR is... like a year, and many have already played/owned/beaten the game and have no reason to repurchase it. Whereas for WWHD, the whole gen gap, means that a whole new line of kids have never played the game.
In terms of raw units, however, I'd put it on TLOUR as it will likely be available to a larger install base.
