As far as games (not sales) go, I see it where the Wii was either in 2010 or 2011. 2010 was a good year for Wii software with Mario Galaxy 2, DKCR, and Kirby's Epic Yarn, and was actually the year its total software sales peaked. 2011 was the Wii's last big year, with support fading as Nintendo prepared its next console for launch, and sales falling as a result.
We already know Nintendo has some heavy-hitters lined up for next year, and I trust they have a great 2015 in the works, as well. 2016 is a big unknown. How will the Wii U sell in that time? Will Nintendo want to continue supporting it for another year, or will they let it go as they prepare to launch new hardware in 2017? I can't answer these questions. I'll have a better idea after the upcoming Holidays.
