Here's a little consolation to those of you, like Eliah, concerned about the Ulduar vehicle fights: Unlike some of the other vehicle fights in the game already, Daelo says on the forums that the vehicles in the next raid will actually scale with gear. He says someone in blues will have a much harder time in the vehicles than someone kitted out in Naxx gear.
Personally, I've only done Oculus, but I do agree with Eliah that putting us in vehicles takes away a lot of the achievement we've gained by leveling and questing -- it's not fun to fail on a boss just because you're trying to deal with a whole new set of abilities you've had no control over until you jumped in the driver's seat. But the fact that the Ulduar vehicles will scale helps a little bit -- players were concerned that every time you went in there, it'd be the same fight, but with new gear that should change. And obviously Blizzard has heard the concerns about the Oculus, so you'd have to hope they wouldn't make the same mistake twice.
Elsewhere on the forums, Zarhym promises, comically, that we'll all enjoy this (and that we'll forget to post how much we enjoy it on the forums afterwards). He says that the fight is different from anything else we've done in the World of Warcraft, and that when all is said and blown up, it'll be an epic encounter. We'll see.
