I agree. As long as it's not officially announced, there is point in discussing it here. The users who hate port-begging should not be hypocrites and should not attempt to derail the thread. Gotta practice what you preach. And there is truth that it could still be console-exclusive to Switch with a PC release like you said. Speculation about further platforms at this point is a waste of time.
Besides, wasn't the original game not received well on other platforms? Swery wanted the Director's Cut to be a bigger success, but the PS3 exclusive didn't do much better than the X360 one, right? So it's not surprising if DP2 never gets ported to other platforms. It'll be exclusive for the same reason as the Collection of Mana and Moon -- being that the games are only viable BECAUSE of the Switch platform.
