There is a Tekken related contest going on at Facebook right now. Basically, you can either remix one of the original songs in the game or provide your own custom artwork. The winning artwork will be featured in the collectors edition art book. I’ve read through all the rules and it doesn’t say that it excludes USA, however it very obviously is a Namco Europe contest (prizes are announced in Euros, and you win the European collectors edition since North American collectors edition hasn’t been announced yet). Waiting to hear back from someone about it, but for now it should be fun to mess around with anyway!
