This is a group of talent that was once part of the small team in the Banjo barn. This was, of course, back in Rare's glory days. These people made huge, multi-million sellers. Banjo-Tooie was actually the N64's final million+ seller not called Mario Party 3! This is a game that was released very late in November 2000 in North America and Japan and released way out in April 2001 in Europe and Oceania as one of Nintendo's last N64 games, even if Rare officially published this sequel themselves.
And look at Banjo-Kazooie, practically a mid-gen N64 game in 1998, and the 10th-best seller on the platform ever with 3.65 million units.
...And DK64 is 7th at over 5.2 million!
If Nintendo truly believes that great software drives hardware (PS2 and PS4's early successes are arguably based on THE PROMISE of good software), then they should finance this project/studio, and ensure a physical release and Nintendo ownership of the IP. People miss GOOD 3D platformers, and sales figures and critical acclaim from the peak of the genre in the 5th generation clearly show that "collect-a-thon" was not a dirty word when done right.
