Mr White To Join "The Office"?

So seeing as Steve Carrell announced that he will be leaving "The Office" after it's 7th season. Looks like the creators are carrying the show on without him. They are planning to bring in a new character to play the new boss of Dunder Mifflin, with "Reservior Dogs" star Harvey Keitel taking on that role.
There has been confirmation by the producers that Keitel is a strong contender for the role, but he is one of many big names auditioning for the role of the new boss. Hopefully we'll find out very soon. But I have a very funny feeling that if they do carry the show in without Carrell, then it will probably get cancelled, just like "Scrubs".
