Well that's what I've been saying the whole time isn't it? Back two years or so estimates already put total PS2 numbers here close to 8m. Total PS3 numbers (counting imported ones, that is) should be close to 1.5m by now and both X360 and Wii around 500k...
Oh, and probably X360 is ahead of Wii. There never has been much love for Nintendo here... SNES was outsold by the Genesis, what on Earth is a N64 or a GC, and Wii was negatively received. Nintendo consoles and handhelds for that matter have always been stuff of skinny japanese descendant kids, or at least that's the feeling you get.
Anyways the numbers doesn't tell the whole picture if you consider Sony should be profiting some $400 in each PS3 sold here (a PS3 costs about $1200 now). Heck even the PS2 is still close to $300. The most insane prices ever were by the Wii launch ($1100 for a Wii, but quickly dropped to $700 or so).
By the way, sales outside of NA and Europe are GOW3's best bet to reach 5m if there isn't any piracy. Pirated GOW and GOW2 had insane attach rates, and at least some of it should convert to 'real' GOW3 sales in the long term.
