To make a sort of related comment, WoW is going down. It might not ever die out completely, or even lose its spot as one of the biggest (if not the biggest) MMO, but it is still going down.
As a long-standing WoW player myself (i recently completely burnt out after my friends stopped playing) i will give a few reasons:
Older players are burning out
It costs what? £60 to get up to date with all the x-pacs and things? this is a serious barrier to entry, especcially on top of the ~£10 a month
Blizzard is not as good as it was; most people agree that it has been f***ed up since the activision merge, and even in the WoW team, a lot of the best devs are leaving for Titan and other companys
WoW is an old game, the graphics and gameplay are starting to look a bit dated already
New competitors: as has been shown, good new MMOs are coming out, such as guild wars 2 and others in the future
Haters are gonna hate, but if you disagree with this post please suggest reasonable arguments against the points made and feel free to add any points you think i may have missed
About SWOTOR: I think that it will be popular to start with but eventually die down to die hard star wars fans, as has been already mentioned
Also, swedish people are cool

some of my best friends are swedish
