I'm not sure what Hotmail does currently, but it won't matter in the long run because the email infrastructure is moving over to Office 365. The DKIM code there will interpret a v=2 as an invalid signature.

All the ones that anyone has checked. Since the code for places like Hotmail isn't available, you'd have to send them some v=2 signatures and see what happens. I haven't done that, although I'd be pretty surprised if they interpreted the spec differently from everyone else.
