Persona 3 FES might be the closest thing, maybe.
It was sold as a standalone release in Japan but there also was some kind of incentive for original Persona 3 users and also a SKU with both the original game with added content and the extra story?
It's been a decade and I'm not too sure anymore, I think duckroll mentioned it (when talking about SMTIV Final sales two years ago)
Anyway I don't really know how the game will be tracked, like will it appear in Famitsu digital monthly chart?
Nintendo probably won't share anything if it doesn't cross 1M too which will probably not happen.
As for Japan 50-75% of Xenoblade 2 sales should be the target (retail+digital).
You need to buy another full price copy, my younger self still hurt from that.
