Is Jeremy Renner taking over mission: Impossible Franchise for Tom Cruise?

We still think that this new one sounds like a horribly-titled disaster, but at least it will pave the way for fresh blood to take over!
Jeremy Renner recently opened up about his new movie, Mission: Impossible - Ghost Protocol, and revealed that his character, Brandt, is potentially set to take over the franchise in lieu of Tom Cruise's Ethan Hunt!
He explains:

"It's a franchise to potentially take over. I can't predict the future and what they want, but that's certainly the idea. I can't really go into the details of the script, because that's still evolving. It's Tom's baby. He's the engine behind the thing. What happens after that, we'll see."

So does "still evolving" mean that it's still being written, depending on what Tommy wants to happen?
Oh, boy. Somebody take this movie out back and shoot it before it's dead on arrival!
This thing could be such a disaster that there won't be a sequel for Renner to headline!
