Fortunately or unfortunately they've been looking at CVC for about 6 years now. It can't even begin to be negotiated till the spinoff of TW is done (if they're saying early 4th qtr I would expect it to not get done till 2nd qtr of next year) and then subjected to all the necessary approvals/procedures in closing, blah blah blah...it'll probably happen a year(s) from now.
Why would it be inevitable? AOL is debt ridden, and it's going to dump a bunch of that on TW because otherwise the spinoff would be pointless (perhaps dumping in the form of taking all the cash from the IPO, forcing TW to borrow). An indebted TW might not be in a position to make any acquisitions, and why would it want another debt-ridden company? Cablevision's problems mean the asset sales will continue, and for a buyer, it makes more sense to buy a useful asset than buy the whole company debts included. Given all that, it mystifies me that anyone sees CVC as a buyout candidate.
