I don't think it's a buyout... I'd guess the discussions centered more around a marketing idea. Selling (perhaps "special versions") Beats merchandise in Apple Stores; or perhaps some special deal similar to the Red campaign... It could be any number of things besides a buyout.
That's my opinion simply because I don't see where the two companies would fit together better than as separate entities. But of course it's possible that Dr Dre and Mr Timmy have some insight that I lack.
