I was wondering when the "remake wave" would hit gaming. we already seen quite a few ports of older games to hit live/psn/nintendo online services, some with minor graphics tweaks.
my feeling was that true remakes would start with the next console generation. Therefore I would be quite surprised to see remakes released towards the end of the current console lifecycle. I think remakes would make perfect launch-titles for the next generation consoles.
But maybe that's exactly what microsoft is going for. they might not be far enough along to show an actual console on E3, but they very well might show a "halo remake" movie to show everyone the graphic level they are shooting for and to "test the water" so to speak to see if there is enough demand to actually play a halo 1 remake.
