They did it with 4 and got quite the return, and VI is more popular the IV was, so it's silly to think it wouldn't give out much of a return.

Not saying it would give out as much as VII, but with it's release on the PSN a year ago, I don't think they'll jump to remake it so soon. They are much more likely to try to milk there biggest money maker as much as possible before pulling out that remake. ;P
