What is it that many of you want from this game or don't want? Story in the way it is presented obviously. Metroid has done true Metroid enough already, it's time for it to evolve. Either that or you guys get another Twilight Princess and your crying for the next 5 years.
What I honestly want from Metroid is a game where there is one giant interconnected level, and I go around and find upgrades that give me special abilities that allow me to access more of the world. That's Metroid.
With Zelda I want more or less the same thing as Metroid only with the presence of non-threatening areas like towns, melee-focused combat vs. shooting, and a fantasy setting instead of a space setting. In fact both series are remarkably similar. Zelda was overhead and Metroid side-scrolling and then that switched to third person vs. first person.
The details are what make a great game or merely a good one. Twilight Princess' problem isn't that the mechanics fit the Zelda definition I gave in the above paragraph. It SHOULD follow that. The problem was that the details were too similar to the details in other Zelda games. So for Metroid I want the core definition I gave above, and hopefully the details don't suck and also are not too similar to other Metroid games.
If they don't **** up that core definition of Metroid the worst we can expect is a good-not-great game.
