As much as I am hyped for part 3, I hope this is just a rumor, and Sony don't go through with this.
1. FF7 in particular has always been a PS game; I think Sony fans deserve to have the first taste
2. Later-release on other platforms always came as more polished version compared to PS launch; I'd rather not experience technical issues
3. I can wait 6 months - 1 year; It really isn't that long of a time
4. I don't want to assume, but this sounds like Sony trying to maximize sales
