It is largely the 8th generation. Right now the only reason PS4 has sold Wii in the same time period is due to Wii's supply issues. Now PS4 is quite a bit behind the Wii on weekly sales and will soon be lagging behind the Wii in the given time period.
On the handheld front, the DS dwarfs everything in the gaming console industry currently.
This generation overall seems like it is going to be much slower than previous generations, and I don't see it lasting as long either. There is good evidence to suggest that the next generation will begin as soon as 2.5 years from now.
I describe myself as a little dose of toxic masculinity.
