I dunno. I like what they've done with the Wii U controller; pretty cool idea to use it as the PDA type device.
Building vehicles... that was one of the funnest parts of Banjo-Kazooie Nuts and Bolts so I hope they execute on this well.
Has there been a Lego game where they talked? I can't remember any talking in the Star Wars or Indiana Jones games... it was just muffled random noises. I don't know if I like it here, probably because the VO didn't strike me as well directed and the script sounded really stupid.
