Hookbill, your tabloid instincts are as strong as ever!
That linked article doesn't say that McKellan is out, only that he hasn't yet signed. I'd be very surprised if they don't reach an agreement.
Regarding the voice of Smaug, the latest items I've read say Bill Nighy is the leading contender. Connery has been retired for some time, although, "never say never". Mike Myers is a joke, right?
