We see the same studios kind of do the same ips, or new studios take the place of others. A big new recruit has been Grezzo. I think after their new IP on 3DS, they will start work on 3D 4 Swords with the BOFW engine. Game has been talked about by Eji. Who else has worked on a MP Zelda? Grezzo's TFH.
Also I believe Team Ninja and NLG are working already on individual Metroid projects. Team Ninja has been very close to Nintendo lately. I think they did the best they could with Hyrule Warriors for it to be compete enough without warranting a sequel. Nintendo wants 2 versions of their IPs now adays. This will please fans of vast tastes. NLG took the place of both the Hunters team and Retro. FF is near completion and by now they are ready to work on their very own solo Prime console experience. Since the artsyle was a problem for some, Nintendo will make a hybrid style of old Prime and FF. Colorful worlds and creatures, but a bit more mature. Why hybrid? Because Nintendo likes to blend old with new. It's how they've transitioned Zelda's art to please both haters and fans of controversial artstyles.
