Just because we're not hearing anything, I wouldn't jump to the conclusion that nothing is happening. If I remember from the last couple of years, this is traditionally a very quiet time as far as actual announcements. With the advent of cell phones, GMs are able to be much more discreet about their conversations and can pretty much make sure they aren't overheard.
Geoff Petrie has a thing about that, anyway, so I'd be very surprised to hear of anything until/unless Petrie wants it released. And I still firmly believe he pretty much warns anyone he's negotiating with that releasing info to the media prematurely is grounds for breach of contract.
