1)
lets see what happens,January will bring out the official sales numbers from all 3
VGC has bad tracking in other parts of the world which leads to difference but every-time official numbers come out VGC adjusts its numbers and then PS3 comes out on top.
VGC's number of PS3 are way below as SONY has projected 15m for this Fiscal year and they have said that they are actually ahead of this numbers but VGC shows that SONY will most likely not be able to make it so there is definitely some tracking problems
2)
Sony's big numbers are revenue(total sales) which differs from profit or loss.
Also the strong YEN makes SONY earn less on every product sold out of JAPAN as currency exchange rates coem into play
As for SONY sustaining it,SONY is a pretty big company so they have alot of money from the past and also it borrows if it needs more and because it has such a great brand,lenders loan money easily.
Sony lost $7b on PS3 from its launch but has been profiting from Q1(Jan-Mar 2010).Its recent losses have come from earthquakes,currency exchange volitality and R&D.
