This generation is up to 70 Million consoles sold as of today between the Xbox 360/PS3/Wii. Since we can pretty much assume that current trends will continue from here until perhaps the earliest realistic date for a PS3 price cut - March 1st. If 20 million consoles were sold last year in this period, then 25 million makes a good estimate for this year assuming the financial crisis makes a big dent. This brings us up to a total of 95 million sold.
The last generation *if we exclude continued PS2 sales* finished at about 140 million console sales in total. So even if the total sales for this gen were to increase to 200 million its still about halfway done at this point in terms of total sales. At the moment its pretty much a given that the Wii will take 50% of the remaining sales at least. So that leaves 50 million to split between the PS3/360, 25 million each at a 50/50 split. To draw level with the Xbox 360 it would require a 27% sales advantage over the Xbox 360, but taking in the current sales ratios it would require a 47% sales swing just to tie. Thats 50 million split 22 million for Xbox 360 and 28 million for PS3.
Thats just to tie, to actually perform anything meaningful a price cut would have to most likely increase sales by over 60% to actually give the PS3 a decent margin over the Xbox 360 and that would require a significant price cut to achieve.
So without mentioning game exclusives unless they have are ensured to sell 4 million + copies or an immediate $100 price slash towards the end of Q1 or the start of Q2 how exactly could the PS3 reverse an assumed win Q4/Q1 2009 for the Xbox 360 and come out with a victory in 2 and a half years or less?
Tease.
