No, because Apple doesn't participate and I think its too early to see a new model come out. Will the Kaby lake processors that the iMac use be out by CES?
It only seems logical for Apple to update the Mini and Pro at least with a spec bump, but Apple has become too unpredictable. I think we'll see new iPad Pros and new iMacs.
I think it's possible that they release an "iMac Pro" that is nothing more than the standard iMac, space grey, slightly higher clock speed, and special version of the magic keyboard with Touch Bar and Touch ID starting at probably $2,899 knowing Apple.
The last January release was in 2006 when MacWorld was still a thing. Apple does fall/spring/summer releases now. February would be an outside possibility but not January. My money is on March-April. Apple gives no craps about CES, lol.
Well starting to see some early reviews of Kaby Lake 7770K which should make it into iMac's. Talks about a Jan 2017 release. So suspect probably about March knowing Apple. Hopefully with some newer GPU as well.
