I think its unlikely since DS is still out in the market and the 3DS is backwards compatible with it.
Heck there arent even GBA games on the eshop yet.
I would think you will get N64 or gamecube games on the WiiU instead. Hopefully they add GBA games to the 3DS in time aswell since they already offered some as compensation, so we know the 3DS can already run them.
