According to Apple Insider, the Mac mini has been moved to EOL status ("End of Life"), so we should expect new models soon.
This popular products for Mac users, but financially not interesting for Apple, might finally evolved and receive new Penryn processors (up to 2.1GHz) as well as the "old new" shared memory graphic chipset GMA X3100. We could also expect the Mac mini to support WiFi 802.11n, it could be a good marketing point for Apple to claim to have all its hardware models supporting the new wireless format.
We should expect the price of the new Mac mini to drop significantly according to the new price policy from Apple Europe.
