Why do you think that?
- Near complete when moved from Wii to Wii U
- Nintendo knows they can't produce shoddy 1st Party titles at launch, following the 3DS' results.
- Nintendo knows people have been waiting on Pikmin 3 for ages, almost guaranteed to get an instant buy.
- Potentially powerful enough to be the only 1st party title needed for launch, alongside all the 3rd party, and whatever Wii U specialised game they have in store.
