I play SWToR - having a blast! It came off to a bad start and people may be right in claiming that RotHC isn't anything more than a large patch. Yet I still have immense fun playing
[Slightly OT] Also, the future of MMOs are F2P model with microtransactions. There is nothing more rewarding (financially) than letting players play for "free" - and by free I mean with more or less restrictions. I personally think WoW is the last subscription only based MMO we'll see.
