Personally i think it is a valid question.
However i don't think it is and if it is then it is very little.
As Nod pointed out about 70% of the gaming market has had numbers release. Not official ones but ones that give us an idea of how it could be. However i have noticed those numbers seem to have increased a bit. Wasen't the UK 265k but now on here people are saying 275k?
The question i think that will help with this is "How big are the additional 30% in terms of software sales?".
As mentioned in the OP "records have been broken". But yet that is not quite the case for the places we know for a fact sell lots of software. For example the UK.
In the UK Gt5 opened to the 6th biggest PS3 launch week. Up 6% on GT4. However what people seem to have missed is that GT5 had its release on weds when in UK releases normally come on a friday. Meaning in comparison to other games it had 2 extra days in its first week of sales that other games didn't have. If you had its first week of fri/sat/sun as is normal then obviously it would of sold less.
It is those sort of things which in my opinion people have fallen into. Again like the AUS article. There were no numbers in the article. No numbers to say what the old records were. Until those numbers are given then we really have no idea of how close the VGC numbers are or not.
Tonight is the NPD numbers. We have GT5 at around 500k for that. If it is over-tracked then personally i think there is a chance others could be too. If the Japanese numbers and US numbers show that it is doing pretty average in comparison to GT4 then i don't think you can say EMEAA should be any different. If we have under tracked GT5 in US then there is clearly a case for the other regions too.
