My prediction is that will be announced by Q2 2018. Bookmark this post, as I was the first one that said it, and it was on December 5th, 2016... Circa HP-Compaq 2001... Companies do crazy things like that in order to extend their lives for a few more years, so I wouldn't be surprised at all...
I also predict that Cisco will spin-off some of their business as well. That's the current trend with the old behemoths, so Cisco is past overdue already.
