Launching on Nov 2005 with 1.5 mil, a year ahead of your competitors in all three major region, is different than launching in Nov 2006 in two region with 1.5 mil a year behind a competitor and week ahead of another. Furthermore, launching and having the next gen market all to yourself for a year is different than launching with a limited supply against two competitors who have ample supply.
That was the going perception but the going perception in the past was that the PS3 would dominate japan. Reality shows us a different picture, so dominating sales in Europe aren't assured.
Thats only post holiday production and in no way indicative of demand.
A bad launch is a bad launch. The X360 also had a limmited supply this is not a new phenomon. Launching early for the X360 is more of a must than an advantage since last gen the Xbox platform was underperforming. Time will tell if this was an advantage...
How can you make a causal connection between 2 totaly different markets (Japan&Europe)?
Demand of the PS3 at this early stage is more of a hypothesis that what may be the case..again the months ahead will gives us some understand towards the demand of the unit.
