I don't get why people keep saying that Rift is bad. I think it's pretty good. It's just the artstyle that is a bit unattractive, I think.
It's too early to say if SW:TOR is a success or failure. It's barely been out for a month. You gotta give it a bit more time than that, although I know how impatient people can be.
Personally, I also hope GW2 is going to be awesome. I liked GW1 a bit, but the playstyle seemed a bit too awkward to me. GW2 seems to remedy that (in my case), so I am very excited about it.
And even though WoW is taboo in these kind of discussions, I still hope MoP is going to make WoW better. Not only because I like WoW, but because a little competition between games could never hurt.
