While it's a shame this and Aonuma's statements mean BOTW2 is still a long way off, as consolations go, this looks a treat.
I enjoyed the first Hyrule Warriors, and a getting a chance to play through the events of the calamity sounds awesome.
As far as it not being high enough caliber to be a holiday game, I think between the pent-up demand for Switch that they still can't quite meet, plus the combined weight of this, Mario Kart Live, etc, they'll have no trouble selling a metric fuckton of Switches this holiday even without a Pokemon/Smash tier title.
