Reports that Apple will be hosting a special media event on September 12th began emerging yesterday. According to multiple reports, Apple will be hosting the event in San Francisco which will be also streamed live to London.

MacOSXRumors now claims that Apple will be revamping the iMac line with the new Core 2 Duo processor at this event, with the additional introduction of a 23" iMac.

Larger iMac form-factor rumors were amongst the reject rumors for pre-WWDC rumors. MacOSXRumors, however, cites "reliable sources" for this report and did have some accurate predictions for Leopard (virtual desktops, tabbed iChat).

Update: Appleinsider also believes that the iMac will see Merom updates in mid-September along with a 23" iMac model.
