Don't forget that this isn't solely limited to the 360 and outside factors (Zune) may hurt/help the division. They've continued to spend money on development and stupidly released the elite instead of just pricedropping to move consoles. I've got plans to buy a premium after a pricedrop if the new processor has rolled out. The elite doesn't stir anything in me to buy it. Most anyone I've heard interested in it already owns a 360.
To cash in my CC rewards points for $300 in Circuit City gift cards to purchase a 360 or not: That is the question.
