There's no way FFXIV is coming to a platform like Switch, if anything they are beefing up the minimum system reqs for the next expansion so something like this is very unlikely.

I won't even go into the potential issues of the underwhelming Nintendo Network with all its limitations.

At best this will be a glorified pokemon console, if they don't RIP the 3DS then it will fail even at that.

Im sorry Nintendo but i don't really see the point of making a console like this, they could just as well make an iPad peripheral and release games for the ios and call it a day.
