Well i think that the problem lies in that the US is rather big. Seeing that a majority of players (results from a previous poll) are in the 13-15 age range and couldn't convince their parents to fly them out to a stupid video game convention. The only real viable solution to this would be having a tour of multiple conventions across the US but that would probably be rather expensive for nabi. If there was a tour it should be like San-Franciso, some midwest city, Chicago, Raleigh, NYC, that way more people who have been loyal to Tb would meet some other fellow players.
Thats just my 2 cents
