Interesting that it's cheaper on PS4 and X1 rather than the Switch. It's probably because it's the newest, hottest console, so making a profit out of it would be smart. But my biggest guess has to be cartridges being expensive to manufacture. Knowing both Rockstar and Nintendo, they will keep their mouths shut for a while and add nothing to this.
I'd just stick with BD or digital. Maybe the latter is less expensive on Switch.
