Now that I gave it some more thought:
Sony) PS2 is going to be put back in the PS3 and Sony wants all models to have it and this will happen in Early March 2010. Since they are getting ready for the new PS3's the current ones can't be produced as much. PS2 will be canceled in Summer 2010.
Microsoft) The Arcade will get a Pricecut to $170 in Late February 2010. This will help hold back Sony until Natal is ready.
Nintendo) The Wii is just popular right now and Nintendo isn't producing as many white Wii's to get ready for the Black Wii in April 2010.
