Going to be expensive for sure though as London is much more expensive than anywhere in the US. A lot of people are going to have to pay a lot more to go if they live anywhere other than Europe. It is much cheaper to fly and stay in the US from places like Asia and South America than it is for them to fly/stay in London. Of course it is much more expensive as well for anyone in the US, which seems to be where a good portion of the players are. I wonder if that will result in lower turn out this year.
I guess the big question now is will rotation happen again before Worlds like last year? My guess is yes, and I would also bet sw & sh 3 will also be legal for that tournament, making it a totally blind meta. It seems like they want to make the playing field more even imo.
