Where is the next VOCALOID concert (in North Americ)?

-I was unable to attend AX 2011 and I am wondering when the next VOCALOID concert in America will be. Thank you. ^^I don't think there will be one any time soon.... The Anime Expo was the most recent one (I guess you know that lol), I don't know that they're planning another one(I haven't seen any dates or advertisements). I really hope they do! I went to the "AX". Too bad you missed it! I really hope they bring Vocaloid back to North America soon! Sorry I couldn't be much help!
There is a Vocaloid Concert in California, LA.....It has past sadly......Couple days ago.... More info on there website....
