The proposed Manny Pacquiao vs. Ricky Hatton fight is off after a Wednesday deadline for the Pacman to sign a contract for the fight expired.

Manny Pacquiao of the Philippines said the much talked-about boxing match against Ricky Hatton of England remains uncertain as the Pacquiao camp takes a hard line stance on their demand for a bigger share of the revenue pie.

In a statement from Pacquiao's adviser and friend Rex Wakee Salud, he said: Manny's stand is the same, he is not fighting unless the numbers moved to his favor.

Pacquiao is demanding 60 percent of fight and pay-per-view purses, a sharing that does not sit well with the sluggers' Hatton camp.

Now that the May 2 showdown is off, many boxing analyst believe that the one that can realistically sell a million PPVs in the U.S., maybe even 1.25-million like Pacquiao-De La Hoya did in their Dream Match fight, is Mayweather vs. Pacquiao for the undisputed pound-for-pound crown.

Thirteen months have passed since Floyd Mayweather Jr. last fight, and Money is ready to come back from his vacation again, presumably in the fall.

After the Dream Match where the Filipino icon Manny Pacquiao totally crushed Oscar De La Hoya into virtual retirement last December 6, 2008, Trainer Floyd Mayweather Sr. said his son, Floyd Jr., has sent feelers to the family that he wants to challenge Pacquiao in a fight that could be a battle for the mythical pound-for-pound title.

The top sport still belongs to the Mayweather-De La Hoya fight last 2007, which Floyd Jr. won via decision. The Dream Match between De La Hoya-Pacquiao is second best grossing non-heavyweight fight in terms of pay-per-view purchases, Top Rank chief Bob Arum said.

Many boxing fans would love to see Mayweather on the ring with the Filipino icon which many believes to become the number one hits off all time in terms of profits.
