Here are the teams I'd prefer made the game
1) Nintendo EPD
A stellar studio that released a brilliant 3D platformer three years ago
2) Ubisoft Montpellier
With plenty of great platformers under its belt, I'd trust Montpellier with the IP. Ancel leaving the industry is a huge blow, however
3) Double Fine
This really all depends on the quality of Psychonauts 2. The original Psychonauts is great -- and probably the best non-Nintendo/Rare 3D platformer -- but that was 15 years ago
From that shortlist, the only viable choice is Double Fine.
I trust neither Rare nor Playtonic to make a good Banjo game.
