AC is made by the Splatoon team, so of course they're going to keep the updates rolling in. AC is the perfect game for drip-feed content too, keeps people engaged throughout the year with new events. Can't wait for the Roost to come back (hopefully in the next update..)
I think it should be other way round right. Wasn't the AC team the Splatoon team? AC has been around a lot longer than Splatoon. Still doesn't give excuse to release incomplete game. Luckily they are saved by the slow nature of AC gameplay.
