AppleInsider points towards a post on its own forums from a source who has historically offered accurate information prior to product launches. The information comes hot on the heels of rumours about iMac and Mac mini updates today.

The source claims that three models of Mac mini will be introduced, one with no optical drive, a 21.5-inch iMac featuring a 16:9 ratio widescreen display and updated Time Capsule and AirPort Extreme base stations.
