Golden Sun DS and Pokemon White/Black have yet to come, so there is at least a little more first-party efforts trickling down until the Fall (when the 3DS may probably come out). Seeing how large the DS userbase is, there will probably be a couple more DS games in early 2011 from Nintendo since they are weaning people off of one console, but managing the other.
The 3rd parties will support the DS for at least another 2 years after the 3DS launch. Especially in Japan, where handhelds have been their lifeline. The 3DS will launch with a couple dozen games and that one Nintendo killer-app. Third parties begin migrating yadda yadda and everything is nice and easy on that side of things.
Now for the Wii.
The Wii...I would imagine Nintendo will continue to support that until Dragon Quest X comes out (which will most likely be 2012) and 3rd parties may do they same. However, I expect them to want to jump ship on the Wii as soon as humanly possibly in order to play around the New Powerful Hardware for the N6/Wii2.
In terms of dev team allocation, Nintendo will outsource more things than they ever have before, and will most likely expand their teams by a sizable amount in order to compensate for the 3DS, then migrate workers from the older hardware to the new one. Iwata said that Nintendo doesn't want to do everything by themselves anymore, or to have to stretch themselves too thin.
3rd parties will (hopefully) take their next console seriously.
