Its a smart move. The more options the better. Also this doesnt sound like a costly experiment either.
I just wish Nintendo drops the support of the 3DS and start bringing dedicated portable only games to Switch instead.
Huh? What are you even talking about? Games that will be playable only in handheld mode?
It's hard to make sense of that statement because Nintendo has no first party games for the 3DS in the pipeline anymore, so everything that is in development is for Switch by now.
