With the new pokemon bundle there is no way Switch won't dominate the holiday seasons (if it wasn't clear already).
You're expecting a $399.99 Switch bundle to dominate the holiday seasons? It'll sell to diehard Nintendo/Pokemon fans and that's about it. There's pretty much zero mass appeal.
Probably comparable to the 500 Million Limited editions of the PS4 Pro, which started at 499.99$ and the full set coming at a whooping 749.99$. And yet they sold out virtually in Nanoseconds.
The bundle is, just like the Splatoon and Odyssey bundles last year, a limited bundle. I don't know how many of them will be produced, but I'm pretty sure they won't last very long.
