just GW2, and D3....but thats not am mmo so none...

If I get GW2, the other MMO I will be playing is PS2 probably. 

none. after try GW2 i just dont care about other MMO

Well I am really enjoying TSW right now. More than I thought I would. More than I enjoyed TOR when it first came out (preordered both). More than any other MMO I've ever played. So much so that honestly I'm not sure how much of GW2 I will be playing. Being FtP I won't be compelled to play it because I would be "wasting money" if I didn't. We will see.

All that being said, I still plan on playing TOR every now and then. Haven't touched it since TSW came out but I'm subbed until middle of next month. I like TOR a lot but right now TSW is actually making me WANT to keep playing just one more mission. Kinda like I used to be when I played any Civilization game. JUST ONE MORE TURN!

FFXIV as long as they don't wowify it too much. 

No plans for any other MMO currently. I generally play only one game at a time.

none why  would i pay money fo another game i wont be playing

when im bored  of GW2  ill look around for something but who knows when that will be it could be  august  2012 or  august 2017 

the only other mmo would consider  buying  while playing  GW2 is another B2P one

For some time none because I'm still vbery bored with the generic mmo's that use the same formula. But I'll probably check LOTRO occasionally because I got a lifetime sub, love the lore and still relate to hobbits having had it as my main character for years.

Since I bought "premium" for BF3, I will probably play that along side GW2 :)

Neverwinter

None.  I am going to just play GW2 for the next couple of years.

Phantasy Star Online 2 !

Well I wont stop playing HoN, maybe Mechwarrior online

Warhammer

I won't create my Silvari Mesmer this year I think. Going to let the big "shiny new game" rush pass by.

That WvsW is way to PVEish for my taste and I don't like instanced PvP so it's going to be mainly Silvary lore and see what I can get out of that Mesmer. For my daily, weekly, monthly, yearly PvP/RvR fix it'll remain waaagh.

TSW, after several betas, and now live, I can't stop playing this game.

Guild Wars, the first one.

Eve Online, i am not sold on GW2 yet though, once the game has been released and i know for sure how the game is going to be run etc. then that will be the time i decide whether or not the game is worth buying, it probably will be.. but if theres one thing i've learned, is never ever pre-order an MMO, if once they release the game there is a free trial, then that would be great, it would at least speed up my decision on whether to buy or not.

PLANETSIDE 2.

Maybe Firefall if that game improves a lot.

GW2 will be my first and if time permits i'll play Planetside 2 and a game i'm also keeping an eye on is Watch Dogs.

Runes of Magic and Shaiya.  Way too busy to play anything that needs a time commitment.
