Versus XIII and a remake of FFVII... you knew someone was going to say that so I thought I would get it out of the way xD.

Back to reality I am not sure re-releasing all the games across the platforms and tacking on an extra disk would be a wise move, after all, there are very few games collectors out there and sales of games has been down recently so I think that just releasing a FF through the ages DVD might be a better alternative, as most of the fans are already likely to have most of the games and won't want to shell out for a new set just for the bonus of a DVD.
