Your statements really have no backbone. The whole Titio-Shamrocks sister thing never even happened, if so provide a link. I watched the whole season 3 of TUF and there was no mention of this.
Ah rumors of Kurt Angle. Dana White isn't dumb, he virtually resurrrected the UFC into what it is today by using his "buisness mind". Plus Angle just signed with TNA.

As far as the cross-over from Japan to the US or vise versa, it happens. But if you have been actually watching MMA within the past year you would have noticed that more stars from Japan are actually coming to the UFC.
