Here's the thing.
A few sites accidentally posted it. One of the most recent accidental announcements showed it coming out in March.
Remember how we all anticipated a full length direct? I think Nintendo is going to announce South Park and GTA5 in that direct.
I anticipate it before the end of the month. Look at how soon after its announcement we got Doom on the Switch. I think this is going to be the pattern for big name, big developer ports going forward.
