Okay so they just made it slightly bigger. I don't know how to feel on the joycons, though. Like with them just being held by that connector alone on either side, doesn't make me think they'll be as secure.
I wouldn't really call this an ushering of a new generation, this just feels more like an suped up Switch model.
At least you'll be able to play nearly all Switch games on it so nothing is that drastic.
