That is a very restricting idea. Just because a developer has made a certain type of game does NOT mean they will incorporate all the values into a different one(especially one with already existing values). Not only that, but they are only helping with some of the 3d areas of the game, they are NOT leading development, and therefore they cannot change the core gameplay. Development is being lead by the same people who made the handheld 2d Metroids, both of which were good games with some flaws. How about you stop judging who is developing the game, but rather the game itself. The game from the point of view of me, somebody who takes this series as the best of the best, as a good addition and might even be one of the best in the series(still worried it will be too linear though).
Edit: Oh and I forgot to mention, the prime series was NEVER meant to succeed the original series rather than to be a sidestory. I'm thrilled to see this game go back to the main series after such a long time.
Edit 2: Also in one of the interviews they mention a third team developing the game called Team M or something like that.
