I'm kinda raising my eyebrow at the Splatoon thing.
When I first saw it in the video, my first thought was "is this a port, or a sequel," because it was short snippets of footage, because the first thing I noticed was hairstyles which seemed like a purely cosmetic change, and because of the existing Emily Rogers rumors, but then I started leaning more and more toward sequel.
The assets are different, the design of the spawn pad is different, the design of the basic core weapons (the Shooter, Roller, and Charger) have been changed, if pants aren't just cosmetic then they'll have perks like all of the other clothing items which would require rebalancing, there's new clothing items, the fact that just the main three weapons were shown as if they're still redesigning every one, the one map shown appears to be either new or an overhauled version of an existing map that's changed enough to cause debate because the geometry, basic layout have been significantly altered and the textures are all different, the team intro animation (if not made up specially for the video) is new with a different camera angle with new poses and animations for the Inklings, and even with a low res angled appearance the lighting and character model geometry seems to be improved.
It might be technically a enhanced rerelease but it would be a serious update if it is.
