Bandai straight up said that they didn't believed that Switch would be accepted that fast and they were looking to ramp up the production on Switch to boost more games in the console starting in april. That was said back in november, just 4 months ago. Games take time to be produced, no one can say for sure if those games listed will make it to Switch, some maybe, some don't, but definitelly have more in store to be revealed for Switch. Be patience,thirds weren't expecting demand for their games after the Wii U-third-party-disaster, you can't blame them for not being prepared for the Switch's success.
Good point. Would like to see Dragon Ball Fighterz on the Switch sometime. Will be getting Dark Souls Remastered on there.
