Retro studios is one of the best developers out there right now, they have made Metroid Prime Trilogy and Donkey Kong Country Returns which are great games, the problem is they are too few and far in between. On average they put out 2 games per generation, if they added a 2nd team they could up that to 4 games and as long as they maintained quality I see no reason why not to.
Imagine one team working on the already announced DKC Tropical Freeze while the other team is hard at work on the new Metroid game. Once those games are complete one team can work on resurrecting another old Nintendo series like Star Fox and F-Zero, while the other team works on a new ip, maybe an open world western styled RPG.
The only thing in my opinion that is holding back Retro from being as great as Naughty Dog is output. If they can put out 3 Uncharted games and Last of Us in a 6 year span while maintaing quality, I see no reason why Retro cant do the same thing.
When the herd loses its way, the shepard must kill the bull that leads them astray.
