i cant understand how ninento and sony can be supply constaint when in november and december they pump out

millions of consoles a week and now there seling about 200-300k a week and they cant keep up whats up with that 

do all there factory workers just have a massive holiday after christmas

and if there short why dont they just hire more workers they only pay the factory workers in cents

They had stocked up for the holiday season and used all the reserves. That is the way I understand it.

They built up stock over the year for the holiday, they thought they'd have more than enough, but they didn't.

They can only make a set amount per week or month..... they make more than is necessary during the slow weeks (so while the Wii might only be selling 300k per week now, they are probably making 350-400k.... though the ones they are making now will take a few weeks to get to stores)

Then the extras that are left over are hoarded for the big weeks of the holiday.

The PS3 is supply contrained because Sony were making a set amount of the new slims, but did not anticipate it to be quite the hit that it is, it will take them a little time to catch up (maybe a few more weeks)

The Wii is supply contrained because Nintendo lowered production levels in 2009 due to the decreasing sales, they had been forced to hoard loads of them.... however the turnaround with Sports Resort/price cut and NSMBWii saw unprecedented Christmas sales, thus they had no stock left after Christmas, it's also possible to air-ship units for emergencies (which means the consoles that were being produced during December were actually sold during december, as opposed to taking a few weeks to ship and sell in January)

Both companies should be catching up soon.
