I personally think Nintendo know the fans want the Gen III remakes, so to give the fans the best possible experience, they'd make sure it's part of the next "3D" Generation.

There's a HUGE difference between Red/Green and FireRed/Leafgreen, as well as Gold/Silver and HeartGold/SoulSilver, but the difference between Ruby/Sapphire and Black/White is not very big at all - both are in full-colour, have animated sprites, etc. Having Gen III in 3D makes the gap that whole lot bigger.
