We are that point in the Switch's life where 3rd party games are starting to pull their weight. The Switch had no big first party title for the holidays and yet stock is in short supply here at the end of February. Instead, Momotaro was the big holiday game, and this week we get 2 titles that sold about 300k combined. 3D World is also selling better than 3D All Stars.
We are not even to Monster Hunter Rise yet! Nintendo needs to step up their shipments to Japan. I doubt they were prepared for the third party titles to do so well, but now that they are, they need to step up these shipments ASAP.
Not just japan, they need to step up shipments period.
