It's no real secret that an iMac update is most likely in the works, but ThinkSecret says they've narrowed down an actual date for the announcement: August 7th. As soon as two and a half weeks from now, we could be seeing a brand new iMac on the Apple Store.
The rumors, as you may have heard, say the new iMac will sport a brushed metal enclosure, to match up to the MacBook Pros and Mac Pros out there, and other sources say the new iMac will include a matching keyboard. ThinkSecret also speculates that iLife may be released earlier than its expected October date (originally, the suite was tracking a release right alongside Leopard). But apparently those rumors are less solid than the iMac release-- iLife and iWork are both supposed to take advantage of new techs in Leopard, so it would be a bad idea to release them early just for the sake of releasing.
As always, don't forget to take that standard grain of salt with all of these rumors. But if you are thinking about picking up an iMac, looks like it might behoove you to wait a week or two just in case.
