I think there are two schools of thought:

Pacquiao looked great against DLH he's gonna beat Hatton (this I believe is totally wrong. DLH was a shell of what he was. Pacquiao was fighting a heavy bag basically, shooting that left cross at will.)

Hatton is far more powerful, he will KO Pacquiao. Lets not underestimate Pacquiao as most of us did when he fought DLH. I think he could do some Hatton-damage. Pacquiao dislikes counterpunches not crowders (I could easily be mistaken here). You see how fast he was? His footwork was incredible and showed no signs of letting up. His lateral movement was also quite good. I need 24/7 to see. I need to see Hatton (I'm going to watch the fight with Paul, I need to see the "new" Hatton with Mayweather Sr). I'll watch that fight and come and make my opinion. Right now I'm undecided.
