Not going to get too excited but
Reading around on a dutch forum and there was talk about a possible 4 man tournament at the Yokohoma vent in March between Spong, Karaev, Saki, and Manhoef.
Now I don't really see this happening for a couple reasons. For one I don't think It's Showtime management along with a couple other management companies would ok it with Spong and Saki fighting in May. Also what really would be a point unless K-1 is coming out with a LHW division and this was for the title. But I would assume if that were the case information would have been leaked out about it.
If it did come true though, that would be a very good tournament. But I still go with the thought that Spong will get matched up against Karaev and Manhoef will get either Saki or Teixiera
