Too bad you skipped the part where Epic says that it is actually not ready enough to be able to release games on switch.
BTW, at the moment, have we seen actual footage of switch games on unreal engines? I wondrr
Though not completely ready, it's official so that's already good news
The link to the article explains everything. The 4.15 update is official UE 4 support for Switch. But its not the final update. Things just got better for Switch developers, and later on, better still.
Hey! They got SONY on my amiibo! Wait a minute. Two great gaming tastes that game great together!
