Apparently I need to spell this out for you.

Thus, it's easier, faster, and substantially less expensive to make changes that hold the logic board shape/size constant.

(Within reason, of course, Apple can do whatever they choose to. Clearly they chose not to add TB3. Maybe it'd have been a simple logic board adjustment. Maybe it'd have required greater changes to the internals. If the latter, then it's possible they really didn't have an expectation of enough sales difference over TB3 to justify the costs. I suspect a very small portion of potential rMB buyers can even spell TB3 let alone tell you why they might want it.)

Yup, you may very well be right, but I think the real answer is as many, including myself, have pointed out. It is a marketing and product differentiation thing first and foremost, with packaging engineering cost savings an added bonus, TB3 is a pro feature first in Apple's eyes, so the MBP will get it first at WWDC, most likely. But even if we have to wait until the Fall for an MBP update, it will still be a good 6-8 months before the rMB gets it as a "me too" feature so Apple can roll out that marketing engine again. Giving the rMB TB3 now would take a lot of the thunder from the upcoming MBP design update. Might even convince myself I need one if they really nail it :)

Oh! I apologize. I'm unsure how that happened. I think I've now fixed it. Sorry about that, thanks for being understanding.

Yes, I agree that marketing and product alignment are likely factors. TB3 is most useful in a "pro" context and thus also somewhat contrary to the apparent thrust of the rMB. I admit I also hadn't realized it wasn't yet available in the MBP line, I guess I thought it was there but admit that I've not paid attention to the MBP specifics.
 
The current Alpine Ridge TB3 chipset uses 15W. The rMB CPU uses 5W on average. No way can Apple afford to power this hungry chip. Next year, TB3 will be baked into the CPU, so everyone has to wait for that in order for TB3 to fit into the power budget.
