I personally feel that there will be a lot of changes coming with Terraria 2. Red orginially made this game in a few months with a limited budget (his own money) and it turned out pretty good. Since the release there have been a handful of updates including the newest 1.2, which basically added an entirely new game worth of stuff onto the original game. Based on this I feel that Terraria 2 will offer a lot of new features, things that couldn't have been put into this game successfully.Undoubtably Red and his team have learned a lot through this games creation and I can only assume Terraria 2 will have much more to offer.

Also with Starbound being made now and it's similarities with Terraria, Red could use the feedback from the players of that game to make Terraria 2 better.
