For those that have been wondering if an event will run during the week of the Arnold Expo it seems like it will be K1

Very cool.
I think it has gone Ufc -> wec -> strikeforce -> k1?
Maybe no ufc 
UFC 96 was there. Then Bowles vs Cruz. Then Henderson v Feijo, and Tate v Rousey last year.
Still haven't heard anything about this event other then it's now Thursday, Feb 28th and is officially announced on the Expo page.
Nothing on the K1 page tho..
