The problem with jumping to a current gen console is the production costs. Let's face it, as cool as it would be to have SE go full out and remake the classic FFs on the PS3, they're highly unlikely to do it. They'll want a quick buck, so they'll put the remakes on a handheld because it won't cost them much to do it, it'll still sell, and they can even contract it out to another developer so they can continue with the series instead of revisiting old ones. Although, its plausible that they could do it on the Wii.

The PSP would be nice, but they've already established a fanbase on the DS for the classic remakes. Switching to the PSP would probably cost them sales.

If FVII gets a remake on the PS3 (which I wouldn't hold my breath on), it'll only be because of the huge demmand for it. The demmand for FFVI on the PS3 isn't that overwelming.
