Yeah probably. Though, somewhere in America would be the best choice no matter what. Fact.
i disagree. No matter where it is, the convention will sell out. Fact. So it being in the US only makes it more convenient for Americans, it doesn't sell extra tickets for the convention. Personally, I think it should be a European event every year, as it is a European product, there is a market plenty big enough in Europe. The US does not need to hog all of the worlds events.
Europe makes sense due to the product origins, also Europe is a cheap travel destination for the most part regardless of where you are coming from in the world.
I would say Aus or far east Asia would be the most expensive overall, so as a second plan I'd also suggest somewhere in the states, preferably not a huge tourist location due to cost of living but not somewhere so remote that the travel details become complicated.
To be honest though if there's a party, geeks and girls I'll be there :), and yeah and minecraft related stuff is a bonus.... But the travel experience and girls win win everytime.
