News Intel's NUC 11's with Tiger Lake CPUs Spotted; Panther Canyon Has PCIe 4.0

I've seen PCIE4 on slides associated with Ice Lake server, but only rumors about support in Tiger Lake. How solid is this pcie4 info on Panther Canyon?
 
So, what I infer from this is that they'll have PCIe 4.0 for graphics, but their chipset will still be 3.0-based.

That's why the dGPU-equipped Phantom Canyon will only have a PCIe 3.0 NVMe slot, while the iGPU-only Panther Canyon will have a PCIe 4.0 NVMe slot, when both are using the same underlying CPU.
 
The Ice Lake gen11 gpu is on a very wide connection to the ring bus, rather than being connected through an internal pcie connection.

Are you saying you expect Tiger Lake Xe gpu to be connected via an internal pcie4?

I suppose that design would be clean for sharing integrated and external gpus, as they claim is possible with Tiger Lake.
