Another Konami title confirmed for Switch.
『ときメモGS4』の対応機種がNintendo Switchに決定 | ゲーム・エンタメ最新情報のファミ通.com
KONAMIは、開発中の学園恋愛シミュレーションゲーム『ときめきメモリアル Girl's Side 4th Heart(ガールズサイド フォースハート)』をNintendo Switch向けに制作中であることを明らかにした。s.famitsu.com
Game was officially announced last year for a 2020 release (no platforms, though).
A Switch release makes sense given how popular Switch is among the female audience (not that Girl's Side isn't popular among other genres as well).
The franchise was pretty popular on DS. 1st Love did 105.091 + 39.610 (Plus version). 2nd Season did 103.110. The Double Pack of both did 8.696. 3rd Story did 165.682. In comparison, Tokimeki Memorial 4 did 99.117 on PSP (including the budget version). These are Famitsu numbers: I'm pretty sure they sold a bit more if we look at Media Create Top 1000.
