Coming from an EDGE interview with Ken Lobb...

The fight, in the pre-internet world, was that we were getting a lot of pressure from fans. Nowadays, you'd be buried under Twitter, NeoGAF — both of which I love, by the way — but those voices are even louder today than they were back then. It comes back to a lesson I learned a long time ago: always listen to your customer, but also understand that if you do focus testing what you're going to hear is, "I want that thing you did last time, because that was awesome." Every once in a while, you have to learn to not listen to that and go, "Actually, Metroid in firstperson we think could make more sense." Great creatives are going to disrupt their earlier designs and make things that are new, or build completely new games or new genres.

It's hard to argue with that logic when you see how great Metroid Prime turned out, as well as the subsequent entries. Now fans are dying for Metroid to get back to the Prime series. Does that mean Nintendo won't do it?!
