PS3 most certainly undertracked.

Yes, the PS3 sold out completely in my area before the PS3 slim launched.

IMO sadly VGChartz has a habbit of overtracking the XBox 360 and undertracking the PS3 on a global scale (this since the beginning). Overtracking and undertracking fluctuate with regard to Japan/US, but for the rest of the world the 360 is usually well overtracked and the PS3 significantly undertracked.

If you add up the numbers VGChartz often claims there are way more PS3s on the shelves at retail than there are 360s on the shelves. This while PS3 (fat) boxes are way bigger and thus that would mean retail dedicating a whole lot more space to the PS3 than to the 360.

But in reality in my country you usually see there are well more 360s left in stock and they are selling slower with various different models. The lowest entry pricing units sell faster than the elite, the 360 is always in stock around here. But I have seen holiday units (119 Euro incl. 19% taxes and with free games) which still weren't sold many months later (they had a sticker covering up the holiday pricing).

Ah, yes. The classic "But... But... it's sold out in my area!

 

Also, your logic about retail space is flawed; what if the 360 had more space than PS3 but was being sold at a higher rate? Oh, right, it is [being sold at a higher rate].
