I'm not saying I don't want immersion, I'd just prefer it not being the primary focus.
If TWW's or PH's vast ocean is Aonuma's idea of immersion, I don't want any of it. That's my biggest gripe about the game by far, and I fear Spirit Tracks may be no different. While it may add immersion, it comes at a cost - an unenjoyable timesink. I know all about this, particularly because I play MMORPG's (a quick google search gets me this, a piece I agree with). I'm the type that prefers the fun to be accessible at all times, and if this means teleporting around the game (hence breaking the immersion), so be it. I just want to be kicking ass as often as possible.
Anyway, it's not that I don't like Twilight Princess, Wind Waker or Ocarina (the immersive Zelda's), they're among my favorite games! However, that's all we've gotten since Ocarina of Time came out. For once, I want to see a game more similar to the original Zelda (admittedly I've been playing it tons recently) - a return to simplicity, and nonstop fun. In an adventure game.
Think of it this way - Ideally I want to be able to buy the Japanese version of the new Zelda, and enjoy it, even though I can't understand Japanese. This is the case with all of the Wii's best selling games, similar to the old NES games (including the NES Zeldas). It's the simple, unchanging arcade style gameplay that allows this. This is in contrast to being loaded with puzzles, mini-games, and cutscenes/text (stories), none of which are found in the NES games. I'm not asking for these elements to be purged completely, but toned down.
Perhaps Nintendo spoiled me with NSMB Wii, but I hope one day, we will see a Zelda game that's closer to the original. As a bonus, I think it'd be better for sales, too.
