There's been a bunch of trailers floating around for K-1 lately and all of them have been touted as official by a lot of people. They were all taken down shortly after though. Now K-1 finally released a trailer themselves, via their Twitter today. They also have a new Youtube channel, K1TVsince2012, which might mean that they actually don't have the original K-1 Youtube account that has been uploading old fight videos lately. They don't have the original K-1 Facebook page so it seems likely. Anyway, check out the new and official trailer for the event on May 27.
