It varies by country - in UK there doesn't seem to be any issues.
I don't know how MS supply - i.e. do they allocate a total amount of units for Europe then split it by country/region based on orders from retailers or do they allocate initial units per country? - but this smells like an allocation issue - i.e. they allocated the right amount for Europe but then didn't allocate it per country correctly, leaving some retailers/places with low/no stock and others with plenty.
Not good support of a major price cut IMHO and I wonder if this Nintendo guy joing in Europe is going to arrive late for the party with too little time to change 360 fortunes in Europe now.
Try to be reasonable... its easier than you think...
