I believe MS has delayed the transition to 6nm because they are still unable to sell off the 7nm wafers they over-ordered.

Then as previously speculated.
The cost of chips at N4 is not high.

This is a much better source then pastebin and a person tha actually works for the industry. Aside from that if it was nearly the same price why wouldn't Microsoft go with 4nm or 5nm? 

8nm Sammy and 5/4nm TSMC are estimated to be nearly the same price after factoring transistor density and increased yields. 

Nobody said TSMC 6nm and TSMC 5/4nm, were (although as prices change and 5/4nm mature they might get closer.) 

Again, Nintendo can't just choose any node. They have to choose the nodes that Nvidia has purchased for their other chips. Nvidia isn't purchasing TSMC 6nm wafers. The options are Sammy 8nm/7nm, or TSMC 5/4nm. 

A (final cost of Sammy 8nm chip) ~= B ( final cost of TSMC 5nm chip) <=/=> B (final cost of TSMC 5nm chip) ~=C  (final cost of TSMC 6nm chip.)
