And the Wii cratered in its later years. Do you think the PS4 will crater in the same way?
The Wii was a beast during its whole lifetime. Yeah the sales saw a huge decline in 2011 and 2012. But in 2011 it still managed to sell over 10ml and in 2012 was its final year since the wii u released that year. The Wii was pretty much a sales beast throughout the whole lifetime.
