Login Servers are going down, not the world server, the world server will go down like usal at its normal time. Account login server is ran diffently this just works out your game time active accounts and bans ect.. this has no tie with the world map.
So no there should not be a roll back from them 3hours otherwise blizz would have a riot on there hands.
Think about it. 3hours playtime > blizz rollback server without warning. Thats raid progress / exp / money all lost. Only time that happens is when the server crashes or theres an in game report notifiying you that the ' Servers will be rolled back due to a technical problem ' Which is extremly rare.
So in short what the topic was about was to say too all those with banned / supended EU Accounts was to let them know if the bug aint been fixed then they will have 3hours tonight in which to strip there baned /supended accounts of any gold and items to send to there other account/s.
Hope this infomation helps clear things up.
