Will Gurumin 3D be release in the european eShop the same day that in the american one? If not, how much will we need to wait? I want to play this game the sooner the better :p

Thank you for your question, and we apologize for not having responded sooner. Yes, Gurumin 3D will be releasing on the eShop for PAL territories, but it will likely be releasing shortly after the North American NTSC version. The two releases won't be too far apart though. :)
