What they've already put into it they've already put into it - it's a sunk cost - but anything from now till when it launches it time/money/effort they could be putting into something else that could well better. E.g. if SE has a FF13 for PS3 that's 1/2 done, and some spin-off for Wii that's 1/4 done, I think the *very* logical thing to do would be to tie-off the PS3 games's development (whether they call it a spin-off at launch or whatever doesn't matter), and put their focus on the one with the biggest sales and profit prospects.
