AM2+ Denebs: Doomed To Die

Perhaps the biggest puzzle is why these chips exist at all. If AM3 chips are supposed to run on AM2+ motherboards, why make AM2+ only chips? Perhaps the reason for that is that AM3 chips were supposed to have both a DDR2 and DDR3 memory controller. Maybe AMD has changed its mind about that, maybe they can't afford to spare the die space. If you say, "Well, AMD will save die space by not including a DDR3 controller in the initial Denebs," well, sure, but they'll save a lot more die space in total by dropping a DDR2 controller from what will be many, many more AM3 Denebs.
