TS4 is getting a complete "refresh" in design and look. I guess TS5 isn't happening soon....

I feel like this is a last-ditch effort to make people forget the game came out nearly five years ago. A lot of fans (although I know it's not all of them) want to move on to the next iteration, so I'm thinking that this might have been done to try to distract them with a new coat of paint - especially after the relatively lackluster reception of Island Living. *edited for spelling.
