The superfight everyone’s been talking about between UFC welterweight champion Georges St.Pierre Vs Strikeforce welterweight champion Nick Diaz has just been confirmed by UFC President Dana White.

“U wanted it! U GOT IT!!! GSP vs DIAZ Oct 29th UFC 137 at Mandalay Bay in Las Vegas,” an excited White posted on Twitter just moments ago.

Rumors of the fight had been building over the past couple of months, but while White had confirmed that it was a fight he would like to put on he had insisted as recently as this past weekend’s UFC 130 event that significant barriers still stood in the way of it becoming a reality.

Even Strikeforce CEO Scott Coker claimed at the weekend that Diaz next fight would be in Strikeforce, but evidently something has happened since and they have been able to come to an agreement.

The fight will pit St.Pierre, considered one of the top pound-for-pound fighters in the world and currently on a nine fight winning streak against Diaz who’s cultivated a 10 fight unbeaten run of his own via Strikeforce, DREAM and Elite XC and built a reputation as one of the most entertaining and exciting fighters in the sport today.

With both fighters now having essentially run out of competition in their respective promotions at 170lbs there’s never been a better time for them to face each other.

Not only is this is a huge fight for everyone concerned, it also has major ramifications for the future of the UFC and Strikeforce.

When the Strikeforce promotion was originally purchased by Zuffa earlier in the year it was claimed that the UFC and Strikeforce would still remain separate entitites and there would be no crossover ‘superfights’ between the two companies.

Today’s announcement means that all bets are off and anything is now possible, with other superfights such as Cain Velasquez Vs Alistair Overeem or Gilbert Melendez Vs Frankie Edgar for instance no longer off the table.

Hopefully in the coming days we’ll discover exactly how the UFC managed to pull this off as even though they now own Strikeforce, the promotion still has a deal with Showtime and the rumor in recent days was that they were not keen on the idea of one of their biggest TV ratings draws being shipped over to the UFC and potentially losing.
