In my opinion, unless this "thaw" results in almost immediate approval...like in the next 5 days... the deal isn't going to close.
As I said in a different post, I'm pretty sure the vultures at big Wall Street law firms are already circling with a class action suit against BC/VMW as they've locked shareholders out of trading. You can do that for a week or two, tops. After that, there are going to be legal ramifications. And once a lawsuit starts, the deal is going to be way more complicated. None of this means the deal can't close, but it needs to happen soon if it's going to happen at all.
Maybe Hock and his merry band should have had SAMR's approval IN WRITING before they jumped the shark. Because you'd think that after waiting for 18 months they'd have gotten a clue that not everything was as copacetic as they were publicly saying.
