If you really want to get more technical about this reveal to release cadence with successors, Nintendo revealed the Nintendo Switch officially October 2016 and released it officially March 2017. That is only six months of reveal to release, but they started doing the mass advertising somewhere in between that period I think, someone correct me if I’m wrong. I suppose the initial reveal was the mass advertising? Who knows?
If anyone thinks that Nintendo needs a year, a year, to announce the product, advertise it and release it needs to get with the program.
It’s 2022 not 2002.
What worked for the DS to 3DS (plot twist: it almost didn’t) ain’t gonna work here.
The Nintendo Wii U was revealed E3 2011, and released end of 2012. That’s overkill.
