You're actually a bit misinformed. The Mario Galaxy series is headed by Yoshiaki Koizumi. Shigeru Miyamoto and Takao Shimizu are involved, but it's Koizumi's baby, and he produced Galaxy 2. There are two teams in Tokyo and the employees can switch back and forth to finish projects. Team 2 made Galaxy 2. It's pretty safe to say that a team has been working on the latest 3D Mario for some time, probably more than 3 years. They have been hiring at Tokyo, and it is no problem to switch employees from EAD Kyoto (there are over 1200 of them) for support. Koji Kondo, for example, who is not part of Team Tokyo, composed most of the music for Galaxy. It is safe to say that if needed the teams on Mario U and MarioKart could grow quite large. 3D Mario and Zelda have pushed the boundaries of every system they have been on, and every system takes more effort and staff. I would expect that the next 3D Mario and Zelda will do the same on the much more powerful Wii U. Nintendo knows it needs to be flawless.
