For PS4 I am thinking $449 too and Sony making a slight loss of $50 on each unit.
Meanwhile MS will sell the weaker X720 for $399 at break-even and thereby attract the casuals and COD kids, who are known to be very price sensitive but poor at judging long term costs like Xbox Live subscriptions. MS strategy is to attract with low entry price and milk them later.
