I guess shipping over 2 million consoles doesnt mean they ramped up production considering there was about 500,000 for launch when they were manufacturing them for months.
I will make this simpler for you
Manufacturing the ps3 for 3-5 months got them 500,000 for launch. December through today put out another 1.5 million on top of the 500,000. They had another company step in to help make blue laser diodes. Thats why production has gone up. I cant make it any simpler for you. Maybe you can print this and bring it to a kintergarden teacher, so she can show you with blocks? I bet if you asked nice she would even show you with beanie babies or little toy soldiers.
