Another 251,794 Wii units were sold by Nintendo in Japan this past May. That would put Wii sales at a 5 to 1 ratio over PS3 sales for the entire month. That’s not the only platform with a 5 to 1 ratio though. The DS managed to sell another 620,670 units while the PSP sold 123,673. It’s like being back in the old days of the NES and Game Boy. I just wonder how long it will last!
