Despite a slow start it’s currently selling at a rate that would allow it to catch the PS4 which is the 5ᵀᴴ most sold console ever. I’m not sure what the guidance was, but even if they were off 4% this last quarter that still puts the PS4 ahead of the Wii by the end of its life.
I doubt a company would ever announce a console is EOL befor their next one is on the shelves. Are you sure that wasn’t about the PS4?
