Probably for the best. I doubt they have the talent and skill to make those "classic Rare" games. Honestly, I think Rare never would have been able to make any of those games without Nintendo having a watchful eye over the process and giving advice.
I don't think they ever had the skill set and they certainly haven't retained this skill set that I never thought existed to begin with. They probably can't make a good shooter anymore and if they wanted to make a Perfect Dark game that peaked above mediocre, the best bet for them is to totally change the gameplay.
Maybe if Nintendo was giving them a thumbs up or thumbs down they could pull out a Goldeneye or Perfect Dark level shooter but that ain't the case. This guy isn't even willing to pretend that it's the case. Those people are gone, those skills are gone, if you want a decent Banjo, it's not gonna be a platformer. We can't make a decent one of those. You want a new Perfect Dark? Be happy with it not being a shooter cuz we suck at making shooters.
The people there now may have talent and skill, but it's not at the genres that blew Rare up during the N64 days.
