Just bought it! Alright, I'll stop the exclamations.
Brief Impressions (keep in mind that I luv Excite Truck, so YMMV):
Graphics are a definite step up. Both tracks and vehicles. I like the bat at the start.
The transformer bug bot thing works for me. Kewl.
Speed is still extreme, though I have not figured out good spots for tree runs yet.
The swingy bars don't get in the way of the racing, which I was slightly worried about
Control is easier, though in normal mode, the buttons of the wiimote face up (not at you)
Difficulty is pretty easy for an Excite Truck vet. Schooling the game so far.
Online is sooooo nice to have.
By the way, not sure whether I beat street date on this by one day.
PS: Some dude named IGN showed up in online, I assume an editor. Schooled that Bum and 4 others to cash in a huge bet. Qt3 shall defend the Excite crown!
PPS: You bonk soccer balls into goals, bonk football thru uprights, get poker cards to get the best hand, smash into bowling pins, craaazy power ups, and if you go into godzilla stomp mode off a ramp, you can freaking glide forever.
