Unless you've read something I didn't, I don't think the return of NVIDIA GPUs will come in the generation to be released on Oct 27. Some Apple internal sources even mentioned Polaris-based MBPs to be announced this fall. Only hope on Oct27 might be if they release a new tower-based MacPro. Other than that, I see the NVIDIA return happening in another future generation, just not now.
Of course, this doesn't exclude that NVIDIA could release Pascal drivers when they update web drivers to 10.12.1.
No one really knows to be honest, but recent job listings from nVidia asking for Apple Metal developers and the upcoming Macs, there is hope for Apple + nVidia relationship.
Also Apple is still supporting the 5,1 Mac which is the last Mac that has upgradeability, so it's highly likely Pascal drivers will come sooner or later.
