Well yes, but I was saying in my post that, if it had been on both, they would have sold even more. They would have sold gangbusters on 3DS and the attach rate on switch would have been mental. It surprised me that they didn't work around the connectivity issues and release USM for both. The connectivity issues were absolutely not insurmountable given that Capcom got full real time cross platform play MH working.
But they only got it working online, not local and contrary to what people believe, local play for Pokémon is huge.
