for DS I think that pokemon and golden sun will be some of the last 1st party games released for it and that they will then move onto the 3DS
internally you've got:
EAD Tokyo, Retro studios, monolith soft, EAD 2, EAD 3, EAD 4, HAL and Project Sora to keep the wii going
so for 3DS you can utilise EAD1, brownie brown, intelligent systems and creatures inc.
Of course, some of those like intelligent systems and monolith will probably work on both systems at once and others like EAD 3 and EAD4 can move over to 3DS (and probably will) once they've completed their wii games.
Once you add outsourcing, which nintendo does a lot, they should be fine
