Did you really expect Arenanet to be keeping alive two MMO's at the same time forever?
This though, can serve as a call for atention for Anet. People will always miss GW1, but I don't think people will ever miss GW2, at least, as much. That says a lot about the sequel...
I actually misread your post - I thought you were planning on importing a copy to play with people in the UK. If what I'm reading is correct, Uncharted 2 and 3 had region-free multiplayer servers, so you'll probably be fine with a UK copy.
I'm guessing you're getting one of their exclusive collector's editions?
Was thinking on taking the standard edition from Zavvi which is 15 € cheaper than in my country. But I could very well end spending a bit more for the collectors edition, although idk if it's worth it. Don't know if Joel or Ellie edition anyways .
