well, there's a bit of third party support right now. Plus i guess many devs were caught off gard by the switch sales. it could be better, but i think that by the end of the year, the support will be really there to stay. i expect a lot of switch title at E3 this year.
beside, Bethesda and Ubisoft seems to really be onboard. so, there's the rumors about fracture but whole that is on the way, Wolfenstein is coming by march i think. i fully expect to see fallout 4 going on switch before the end of the year. I really hope to see NHL for switch in september, and probably madden, but EA doesnt seems to like nintendo a lot.
