Yes it is in my oppinion.
Now, of course how to define a generation is mainly based on personnal oppinion even if people want to argue for hours (or page) that they "know" the right definition.
And in my oppinion, as well as several others, a generation is more a console cycle; pretty tied to their release date when they are close by a year or 2 and the new software library or concepts.
Based on that, I see the Nintendo Switch as a new generation (and a very awesome one knowing everything we know about the Switch:)).
