Different planets?

Because of the style of game, is it going to be like "land on any planet whenever you want" or just land here cuz some mission says so. I hope they go for the land whenever and wherever approach, it would have more of a sense of discovery when you find something cool, or meet a race.

I was just wondering how you guys think it will turn out.

One more thing, do you guys think the planets will be varied enough? I'm afraid it will be like do a few missions, find a couple collectibles, meet the race that lives here, do some missions and then fuck off to the next planet. Which may get repetitive. Now, I'm not criticizing the game. And I have faith the bioware will make a fucking fantastic game out of this. I have full faith in them. I'm just wondering what you guys may think.
