Yes, but I think the reception will be very split. I wouldn't be surprised if we had to wait another year, as well, maybe with the release of an updated Switch.
I don't think there's much they can do to improve style-wise. I'd love graphics along the lines MK8's Animal Crossing stage, but even that feels a little unrealistic to ask for in the scope of an entire game. A consistent trend for AC is elongating and detailing the human character models per release to the main title, but how much more can they while maintaining the nostalgic quality everyone has come to expect?
If they neglect updating this aspect, people will be furious with accusations of a near-port.
New Leaf was such an amazing improvement from City Folk that I think this release is doomed to disappoint many fans, especially with the brand new audience NL's success managed to acquire. All of us want such specific changes.
