If Sony gets FFVII Remake, they won't need a price cut. Agreed?

I'm just curious, how many Final Fantasy fans don't already have a PS3 in anticipation of FFXIII? Furthermore, what proportion of fans would by a PS3 for an FFVII remake but would NOT buy one for FFXIII? The point I'm trying to make here, is that whatever sales an FFVII remake might induce could well be made by cannibalising the potential system sales induced by FFXIII. This is because the two games probably share a large part of their fanbase (in much the same way as Mario and Zelda often share much of their fanbase).
