I can't imagine this system NOT including those two fees.
A fee for transactions and a fee for actually taking money out of your account? Why WOULDN'T these exist? Why would they do this system for free? That's a lot of money they will be responsible for until the end of Diablo 3, why the hell wouldn't they exact a toll to do it?
Plus an income stream from the game means they will have resources to actually update it like WoW is. Diablo 2 gets updates, but aside from the synergy patch none of it has ever been much of an effort on their part, because it wouldn't earn them anything.
