Has there ever been so many consoles on the market?

[legend92(3)]

So there's currently 10 cosnoles on the market right now.

6 Home consoles Wii, Wii U, PS3, PS4, X360 and the XOne. 

4 Handheld consoles: PSP, PSV, DS and 3DS.

I was wondering if there has ever been that many on the market at the same time. Also what year do you expect the "Last Gen" consoles to be discontinued. 

I think the DS in '14, PSP in '14. I think the Wii has? X360 in '15 and PS3 in '17
