I'm not saying your a dumb shit, but I think you are wrong about this huge conspiracy and fake shortages - if only for the reason that why would Nintendo benefit more from selling Wii's or DS's AFTER Christmas rather than before?
The Christmas selling period is one that has always held more kudos, and the shortage of Wiis (and the price hikes of the ones that are available) mean that right now in the UK it's cheaper (yes cheaper!) to buy a PS3 than it is a Wii from real "bricks and mortar" shops.
This isn't a good thing for Nintendo, so why would they create a false shortage? It doesn't make sense.
The Wii is in short supply because they are are so damn fun, every family wants one. There physically aren't enough of them to go round.
I feel sorry for those that have to plump for a PS3.... the shame!
