The Nvidia Drake model (T239) that's been leaked (also by a leaker who's gotten multiple things correct) and is listed as NVN2 in an Nvidia leak (NVN is Nvidia's internal firmware name for the Nintendo Switch) is way too powerful for a "Pro" model. That thing is like 6-8x more powerful than the current Switch.
That said I doubt hardware this year. Furukawa said point blank he doesn't think hardware initiatives will boost Switch sales this year, that seems like a weird thing to say if you're launch new hardware.
This leak could be correct and still be a 2024 product as this Pokemon DLC runs through April 2024.
