In the same month of November, in Europe, PS3 outsold Xbox by a margin of about 215,000. Yep, that's about twice the margin of victory MS had in America. In Japan, in the same period, PS3 outsold Xbox by about 140,000 units. And the fun ain't over yet. In November, in terms of units sold in markets outside Europe, America & Japan, PS3 sold about 740,000 units (as much as it sold in US), while Xbox sold 500,000. That again gives Sony a 240,000 margin of victory.
Now, add up all the numbers, and you see that overall, in the month of November, Sony sold about 500,000 more consoles than Microsoft. That's about… (Sigh)… half a million!
