We had the Cube, the Cylinder, this time around it will be the Sphere, no doubt

Imagine something in the lines of the Death Star...
We could have the power switch at the top, with finger print recognition (a la rMBP).
Ports at the back, vertically aligned. Apple logo at the front.
The rTB3D would have Face ID (skip the notch please) and embedded T3. The Sphere would also have to have a T3.
If using both the Sphere along with rTB3D both T3s would have a secure channel (through TB3 probably, but that could raise security concerns - heavily encrypted comm) for authentication. If you use a regular display then only the Sphere's T3 would assume authentication.
Cool, hem?!
Feel free to do some sketches.
But I guess that would go against the box everyone here wants, right?
You could still open the Sphere and insert or swap (proprietary) GPUs, that would make it upgradable and modular, right?
[doublepost=1527950032][/doublepost]The wait for Cascade Lake makes sense for Apple. Launching something now that could have potential important fixes in a few months would be unwise.
And as dec says, the engineering could be all done now, and probably and hopefully well underway, and when all is ready just drop in.
