IMO currently the primary switch limitation is storage. Switch core storage actually is quite small. A game like FFXIV would require expanding it with a micro SD card. The cause of this is that at its core the switch is really a handheld system like the DS and was a move to essentially go from having separate console and handheld systems into just having a single hardware piece. What I would probably ask for more than FFXIV on switch would be for them to finally port Dragon Quest X outside Japan on that console since it was originally on either the Wii or Wii U.
