Very doubtful indeed - I think PA will remain the pre-req for Cleave.
The main effect of this is to stop monsters taking the Blackguard class when they have the Cleave feat as a bonus feat, without needing to take Power Attack first.
Yea, I absolutely love the new blackguard picture. The one in the original DMG made me want to cry. The Epic Level Blackguard picture was great though, and so is this new one.
