The fact that this game releases later on the Switch shows that they added it late too development. Which is interesting. Even Sega got in a bit late. Anyway this title is a strategy rpg set in WW 2? Sounds interesting.
That's not necessarily the case. If PS4 is the game's lead platform, then it would require more time and resources to make the Switch version. Especially if it's targeting 30fps on PS4. That is unless you want a broken mess running worse than Dragon Quest Heroes.
