That's a good thing! Means we might get something with some actual guts.
A possible Tegra X2 with 512 Pascal cores at a decent frequency should EASILY match the Xbone with its 768 GCN 1.0 SP's. Also keep in mind, Xbone only has 68GB/sec DDR3 memory interface.
Does anyone know the current bandwidth of the Tegra X1?
From what I know, mobile systems are almost always memory hamstrung due to narrow interfaces that save power. Maybe it will have a clever ED-RAM like Xbox has used for the past two generations.
Here a 750ti with 640 Maxwell cores beats out a 7850 Pitcairn (almost exact same as PS4) with its 1024 GCN SP's.

750 TI has 86.4GB/sec, about 20% more than the Xbox One.
Tegra X1 on the 20nm process with 256 Maxwell cores has a 25.6 GB/s memory bandwidth.
If Nvidia can improve with 512 Pascal cores with a beefed up memory interface to maybe 40-50GB/s then they can definitely match the current console generation.
All that to say, even though I harp on Nvidia for vulture pricing, they are one of the best engineering firms in the world, and if they can build an incredible mobile SoC for Nintendo then I think the big N still has a chance.
