On the topic of Halo 4 as a "system seller" ...
While there will (no doubt) be an increase in sales associated with this title, I'm doubtful that it will be very long lasting because there have already been many Halo titles released for the XBox 360. Between Halo 3, Halo Reach, and Halo ODST I'm pretty sure that most people who are interested in the Halo franchise already own an XBox 360.
