Will collective sales of the 8th gen manage to match 7th gen?

I think 7 was the consoles luck number 7 and collective sales peaked then. PS4 might sell more than PS3 but won't sell more than Wii (not by much at least), XB1 will not sell more than 360 and Wii U won't sell as much as Wii (pretty obvious)
