instead of "think different" how about you "think about releasing a modular Mac pro at a competitive price point"
Apple is more likely to discontinue the Mac Pro than they are to admit that the price and configuration options are the problem.
They’ll say the new model didn’t prove to be successful. And of course it likely won’t be if the price starts over $5000, and the configuration is too lean at that price (not to mention that it’s going to take a while to win back the market they’ve lost during their stagnation).
So I expect it very likely that the modular Mac Pro (if it’s not just vaporware) will likely be a one hit and done.
They’ll say that sales have been poor for the last two revisions (Modular Mac Pro and Trashcan Pro), and therefore it’s time to discontinue it.
Of course, failing to realize that the death of the product is their own fault, and not a shift of Pro users moving to tablets.
