CJ, Petz - I'm relatively clueless here, but if they were to do this(castrate K8), wouldn't it be more likely that they would just force one of the legacy modes or disable the long mode? At least initially, with die changes made in the future if there were substantial size/cost savings to be had?

PS. This still seems like a bizarre product to me. To castrate it on capabilities rather than performance seems unwise.
