ThinkSecret pinpoints Tuesday, August 7th as the likely date for the long awaited iMac revision.
The revamped iMac will represent the first substantial upgrade to the system since it initially adopted Intel processors in January 2006, and will sport an entirely new brushed aluminum enclosure.
ThinkSecret also suggests that the overdue iLife updates could also arrive at the same time, but are less certain on this possibility.
A recent rumor had claimed that iLife update had gone "golden master", suggesting an imminent release.
Update: Meanwhile, 9to5mac.com independently posted an update also claiming that August 7th was the date for the new iMacs and probably new iPods.
Contrary to previous reports, they claim that the iMac will come in a 17" config as well as 20" and 24" varieties. The iMac is described to have a metal "razor thin" enclosure and revised keyboard with additional media control functionality.
Their information on the Video iPods claim shorter and wider iPods (mockup posted) which still uses the traditional click-wheel design, rather than a new full-screen design that people have been expecting.
9to5mac is relative new to the Mac rumor world, but has had legitimate information in the past and were the first to claim a brushed metal look to the upcoming iMac.
