It's not that impresive we know that handheld are more popular then home console and ps3 has a slow debut i will call 3DS impresive if it outsell ps1 and ps2.
PS4 - over 100 millions let's say 120m
Xbox One - 70m
Wii U - 25m
Vita - 15m if it will not get Final Fantasy Kingdoms Heart and Monster Hunter 20m otherwise
3DS - 80m
