We've known since the game was announced that they wouldn't be able to do splitscreen since they're pushing the tech so hard (and it apparently wouldn't scale down well). LAN was a possibility but frankly it's a niche that doesn't intersect very much with most of the Wii userbase anyway (it's mostly for college dorms).
Most of the time you see pubs pushing online over splitscreen because online requires every player to buy the game, while splitscreen only requires one copy of the game for four people. I don't think that's the case here, though, and you'll probably see it if we get a sequel.
