I am curious whether this rules out a 14nm variant of Orbis. There's still the part of the market that slim models have typically targeted with cheaper, smaller, and quieter models. The upclock and GPU expansion would seemingly hurt on all those counts.
Has the current gen somehow already cut into this? Does the 28nm PS4 serve as the volume play?
In theory, a Neo in legacy mode could act much like a slim model in terms of thermals, but unless the box and cooling solution can grow and shrink on the fly the product cannot reflect that externally.
