People like to ignore that alot of X-BOX, PS2 (and now PSP) #'s get boosted when they get carried in much higher percentages of rentalors than Nintendo games do. If Nintendo had equal presense in these sectors, then thier software (and most likely hardware) #'s would also increase.
A sale is a sale is a sale...and when a 5000+ store chain like Blockbuster buys about 50+ PSP games per store to rent you see that software #'s are boosted for PSP. There was a jump in software sales the month after Blockbuster decided to carry PSP games.
This plus factoring in other rentalor's all while excluding certain huge retailor's (WalMart) and adding in the shipped vs sold spin make sales #'s meaningless.
If I can go if a ranting tangent:
I wish Nintendo would wake up thier damned reps and send them out to places like Blockbuster and SEE how DEAD Nintendo is to the mainstream gamer. Stuffed in a back corner, dwindling away into nothingness...and this only hurts thier image. MS does an excellent job representing themselves at rentailor outlets and Sony gets the benifit of the doubt 'cos they have the popularity behind the PlayStation name as clout. Nintendo get's shafted. If I were working at NOA and had the power to I would demand that GBA games & NDS games would've been carried at Blockbuster months (and in the case of GBA, years) ago. And that they'd carry a proper amount of the right games too. The GCN needs alot better treatment too, earlier in it's lifespan games that came out across all three platforms would come in for X-BOX & PS2, but would not come in for GCN...this gave the image that certain games didn't even exist on GCN when, in fact, they did. It was downhill from there...in my Dayton, Ohio (mainstream U.S.A.) district NONE of the stores got Legend Of Zelda 4 Swords and all of the stores got ONE...ONE...ONE copy of RE4! It's assinine, I blame Blockbuster for shafting Nintendo and Nintendo for not even caring about thier presence at Blockbuster.
