I don't Play WoW.... THANK GOD!
I gave up on WoW a long time ago, it's a good game and deserve the credit it got but man, was that game boring as hell at times and repetitive. I will be playing SW:TOR. As for it challenging WoW, well to be fair WoW is slowly falling and I think Blizzard know that. So for me yes, but it is to early and I suspect WoW will be pretty dead anyway when SW:TOR comes out.
