1- Are there going to be tents set up to meet with pro teams for pictures and signing.
Last year in Brussels (Semifinals) and Berlin (Finals), there were a few players standing outside that you could say hi to if you stood in a line that took 10 years. Rivington was also posing for pictures with fans in Brussels. There were no official tents however. There was one for facepaint and one for merchandise in Berlin.
2- Any free gifts for showing up?
inflatable thunder sticks and a rubber bracelet were what was given out in Semifinals and Finals last year for showing up and getting in.
3 - Is there going to be a shop with rito merchandise?
Yes. Expect insane lines however, and they sell out of the popular stuff fast. There were also electronic kiosks where you could order store merch to be shipped to you.
