Would an "Old School Rare" game even sell these days?

I think a proper Banjo Kazooie game could probably shift 3 or 4 Million units in the long run, if done right.

People still like platformers, the problem is that outside of Nintendo we get so few actual quality efforts. Look at what Sony achieved with LittleBigPlanet and what the LEGO games manage to push. There is a market for the action platformer.
