It's not more than a remaster, it's more than a straight port, that's it.
If you compare it to movies, it would be a remake if they redid the motion capture, voice acting and rebuild all the levels. Story and game play can still stay the same. This is still a remaster. Movie remasters also touch up the artwork by removing blemishes, enhancing colors, balancing black level and contrast, converting the sound to 5.1 or 7.1 and encoding sound and picture at a higher resolution. Games can enhance the character models by using ones with higher detail ones retaken from the original models, movies scan the 35mm prints in 4k to get more detail. It's all remasters.
It looks like a good remaster, and I wouldn't mind playing the series again in 1080p60 without motion blur! Yet not for the $75 it is listed at in Canada. Maybe in a few years as a platinum edition for $30. Mario maker, MGS5 and Fallout come first.
