@danj can you confirm this?

No one realize it doesn’t have a PCH? It’s only the T2 chip. So T2 is a PCH technically.

I wonder is the butterfly 2 actually "rubber-free?" Which means it's all plastic, so there's no worry about the aging.

Perhaps an eDRAM with integrated Graphics would make the MacBook Pro "GDDR-free", therefore it's possible to put more RAM chip on it.

It's probably not the same design as the touch bar version, as this one much like a improved version of the rMBP13, while the touch bar version are having different lengths of blades (as official website suggested). I'm interested to see what the touch bar version offers.
