Dennis Sellers of MacsimumNews has gone out on a limb today and predicted that both the iMac and the long stagnant Mac mini will see an update on November 10th (a Monday). But also goes onto state that a Mac Pro update will come at Macworld in January, not the normal destination for a pro orientated product release.
Sellers who makes no mention of sources goes onto to explain that Apple will want to ship new Pro desktops that will work with a new line of Cinema Displays that will feature the Mini DisplayPort connection. Adding that Apple will release new Cinema Displays at sizes of 20, 24 and 30-inches. This would be in addition to the current 23-inch model.
Finally Sellers leaves us hanging by noting that this is not all that Apple will announce at Macworld which runs from 5 - 9 January 2009.
