Hm. The mandatory internet connection seemed obvious, after SC2. It's how they're beginning to roll. I don't mind, since my connection's always active, but...hey, options are never a bad thing. Especially for a game with strong single-player offline content in its history.
As for the real-money auctionhouse...now that's a huge shocker, coming from a company who has repeatedly denounced players selling in-game items for real-world currency and claimed that games are for fun, and that allowing players to spend real-world wealth to gain something over other players is unfair and immoral. Though, given how much they've pushed their in-game item shop for WoW, I guess it makes sense. *Sigh*
