I thought it could pre launch but now after the fact I don't think so.
I'm looking at titles coming up for the 3DS or just released and can't help but think they would have had a better home on the Switch and not just something to release on the 3DS for the sake of releasing something.
2 examples are Mario Sports Superstars and Tank Troopers.
Mario Sports while not an amazing game looks like it could have been a nice launch month title to play via for something other than Zelda. Games like Tennis and Soccer could have shone as local multiplayer games with the 2 Joycons. Golf could have been a great game to play on either handheld or the TV, maybe even add in motion controls for it. I know it's not perfect but releasing it at this stage in the 3DS after it already has similar games seems pointless. On the Switch it would be a great filler game for people starved of things to play, on the 3DS its just a subpar game on a system with heaps of amazing titles.
Tank Troopers is a strange title, the multiplayer is local only and while the single player is fun, i can gaurentee you its been ignored this late in the 3DSs life. Now imagine it had of come to the Switch, a new IP to show off the system, a local multiplayer game to play with friends and maybe even online if that could add it. Would of been a nice fun multiplayer game to keep people happy until Splatoon comes out. At this stage no one is really playing attention to the 3DS, but in the Switch or could have been a thing.
I do see the need to keep content coming to the 3DS, but honestly I really do think they should be scaling back alot more just so the Switch has more content and the games don't get ignored.
