Elaborate April fools joke from the Yakuza team..or is it? TurnBased combat in next Yakuza?(or mini game)

[Megiddo]

That is way too elaborate and time-consuming to just be a one-off April Fools prank.

It will almost for certain be in some form in Shin Yakuza, most likely as a mini-game sort of thing like the Majima construction stuff.
