What will make more $$ a month, WOW or Diablo3?

It's possible Diablo 3 will, but it comes down to one simple fact: Will Paypal charge their normal transfer out fees? Because if this is the case, we're doomed. I remember trying to transfer money that I had put into Paypal, back into my bank account. I didn't know they would charge an amount of money for the transfer; after the job was done, I was left owing Paypal. Do people know enough of Paypal's business ethics to place their faith in them? The answer is NO. I'm afraid if Paypal doesn't wise up, then Act/Blizzards profits will dry up and Paypal/Ebay will lose out on profits at the same time. I can't say if Diablo 3 will earn more cash than WOW within 3 months time.  My crystal ball is broken.
