Unless IGA remakes them HIS way, which would mean a revamped story and a different placing in the timeline(so they wouldn't conflict with other games), none of the retconned games will EVER be remade on IGA's watch. And, even if he DID(and it's the way I described above), original fans would be pissed. I can be sure IGA would remove some characters, maybe get rid of Nathan altogether(and put someone like Richter into the game).
