Well I don't want a remake, because knowing Gamefreak they'll make it with all the flaws RSE had, which was the case with FRLG and to a lesser extent HGSS.
One thing that weighs heavily against RSE remakes, though, is that the mechanics of the game are mostly unchanged from RSE to B2W2. For the most part it would be playing the same game as the original. The only major addition was the physical/special split in DPPt, but would that by itself warrant an RSE remake? I don't think so. They may introduce a major mechanic overhaul in gen 6 which would even block compatibility with gen 5 (incredibly unlikely), but who knows.
