You do know that there is a cost to develop for PC then on PS/Xbox to be packed in dev kits to make them run.
Pc you have to develop individualy,PS4/Xbox they all have their individial Dev kits they cost they aren't given for free.
I don't know but shit ton of games on Ps4/Xbox passed a million easy and they were full triple a multiplat games.
Actually there are quite a few that are given for free and I have no doubt at all that if Nintendo wanted to develop on one of the other consoles they`d get free dev kits. Besides, aren`t they making Switch games with UE4 now anyway?
I don't think so they have their own engines for their hardware,i think Switch will be Supporting games build on UE4.
Well it's all speculation,but the fact of the matter is they aren't gonna make any games for anything else for a foreseeable future and it depends very little if the switch fails,and i wouldn't want it any other way as long as the competition is healthy everything is good.
Pretty sure Big companies have back up plans when shit hits the fan if it came to shutting down but who knows.
