I think it's unlikely that Apple is releasing a new designed 16" MacBookPro just together with the MacPro. Considering they fixed the heat and keyboard problems and added a great 16" Monitor with a powerful GPU, many Pros might choose the MacBookPro instead of the MacPro as there is no "Mac" at a $3500 price range. $6000 is just a lot of money if you just need a replacement for a 5,1 and not using the MacPro for high level calculating.
