People stupidly callRetro the new rare just because they took the challenge of a new DKC.
Retro started with a few members of team known as Iguana, the developers of Turok series for Nintendo 64. Retro has pushed boundaries as well with the amazing things they did with Metroid Prime. So thay are an amazing development company on their own right.
Development teams were smaller back in the day, so many projects could be done in a short time span between titles, but things are way differnt nowadays. So the comparison of number of titles in different periods is invalid. Both are good in their respective times with Nintendo.
Thsy are different companies. But I do agree that the only Nintendo company that can develop a DKC and revive the franchise is Retro
