They may phase out the non retina 27" model if they have manufacturing under control. I suspect the primary reason for having both is to moderate any ramp up issues they might have.I really doubt that Apple will drop TB anytime soon. TB and USB-C serve different needs entirely, especially in "PRO" hardware. The fact that many here don't understand that doesn't mean that Apple doesn't grasp the issue. If anything we might see TB 3 hardware this year.
