The N64's tally of 33 million will soon be overtaken within a few weeks. The Xmas period will yield around 9 to 11 million Wii sales. So Wii will finish around 46 million at the close of the year.
A lifetime tally of 160 million Wii consoles is possible that would equal the combined tally of the previous Nintendo consoles: NES(61m), SNES(44m), N64(33m) and GC(22m).
