Some are speculating that eMacs may be updated due to their listing under "Previous Generation eMacs" in Apple's Special Deals page. But this small change alone does not appear to be convincing evidence of updates.
That being said, an anonymous unconfirmed report previously sent to MacRumors had claimed that eMacs would be discontinued in January with the introduction of a new iMac. The validity of this anonymous report is completely unknown and only published as possible color to the above speculation.
