4 X360 Feb 06 187,250 1,117,000 PS3 Feb 07 133,750 1,160,500
In japan you get ps3 for 500$, and now it outsells xbox360 + with low shippements of wii, almost reached wii, 30k vs 40k for last week.
and now in europe it will be selling for J425 = 850$ in UK, and other countrries for 600Eu = 800$. And people will buy.
OK now to the point:
YOU BUY PS3 FOR 5 YEARS, MINIMUM.
5 YEARS = 60 MONTH.
YOU LIVE IN USA: 600$/60 MONTH = 10$/MONTHLY, IS THAT MUCH FOR SUCH PEACE OF TECHNOLOGY? WHICH CAN PLAY AMAZING GAMES + YOU CAN WATCH FULL HD MOOVIES.
YOU LIVE IN EUROPE: 800$/60 MONTH = ~14$/MONTHLY.
HOW MUCH COST YOUR MOBILE? HOW OFTEN YOU CHANGE IT?
What for me, i going to buy PS3, when it gets rumble in sixaxis + chip that plays all region blu-ray disk, 
or when FFXIII released. :) BECAUSE TODAY I STILL HAVE WHAT TO PLAY ON MY PS2.
