By "Rainbow Version" do you mean one of those will probably never happen all-region games?
Live with the fact that is highly unlikely. So long as the series sells, they will continue with the 1 or 2 region hand-held console titles probably until there are so many regions that a cover-all game would be incomprehensibly idiotic.
Though in reality it is idiotic now, as a game that covers all regions and has access to all Pokemon would be boring and almost completely erode all motivation for people to trade with each other.
Plus, hand-held consoles don't have the storage capacity for something like that at anything other than ridiculously pathetic quality. --- We shall rise again to start anew. White FC: 0862-2660-4156 / 3DS FC: 2492-4470-1418 / White 2 FC: 4556-7836-2644

That could be easily done unless they had full voice acting or something. B/W was only 256MB. 3DS carts are available in up to 8GB capacities. --- Alienware M17x R4 | i7-3720QM | 2GB 7970M | 16GB DDR3-1600 | 128GB Samsung PM830 mSATA SSD
