It does not require an internet connection to play on single player, there's full modding support with the Torchlight 2 editor, and you can bring your character from single player to multiplayer and back at any time. And just like the first game it's not going to be a full 60 dollars release.
Youtuber Totalbiscuit is currently working on bringing 3 very long Torchlight 2 videos from Gamescom to his channel. First two parts with gameplay commentated by lead designer Max Schaefer, and the third one some gameplay by TB himself. Which should give us a lot of new info.
