Lots devs has PS3/360 engines you know. Those can likely easily port to the Switch.
Don't assume "developer support" means all the latest and greatest games. Skyrim (a 5 year old game) being the most heavily emphasized third party game in the trailer probably was a pretty big tip off.
Why the hell would you choose to demo your brand new game system with a 5 year old game? It's because those are the types of games the Switch will actually be getting.
