What else can it be? Switch having custom Tegra X2 is pretty much confirmed. Tegra X2 isnt too bad, but it's definitely not as powerful as PSXB.
The only "better" thing that can happen is that Switch to use volta-based Tegra Xavier, announced by Nvidia in September, which has a pretty low chance to actually happen.
