Rhodey Recast?

The Hollywood Reporter is claiming that the character of Rhody aka War Machine has gone from Terrence Howard to Don Cheadle for the Iron Man sequel.

Marvel had no comment, but sources close to the deal said negotiations with Howard fell through over financial differences, among other reasons. Marvel,
which had wanted to work with Cheadle, then decided to take the role in another direction and approached the actor, who is shooting Antoine Fuqua’s “Brooklyn’s Finest” with Richard Gere and Ethan Hawke.

At first I found it somewhat shocking, but the “Marvel has no comment”, gives me the sense of disbelief. if this were true, I find this positively shocking.
