Amazon Germany, according to 9to5 Mac, has leaked details about Apple's next version of iLife (presumed to be iLife '11). The store listed the ship date in a popup box in the store sidebar, noting that it would ship on October 20th, which is the same day as the Back to the Mac event that Apple is holding.
The blog also notes that Amazon US has a lower $49.99 price point, leading us to believe that Apple may be lowering the price of the new version of iLife.
BestBuy is also currently back ordered on both iWork '09 and iLife '09.
While this is clearly speculation, Apple is due to release a new version of iLife (and possibly iWork) as we are still running iLife/iWork '09, which was released in January of 2009.
Stay tuned to Mac|Life for more information leading up to the Apple "Back to the Mac" event on Wednesday, October 20, 2010. We will be liveblogging the event right from here.
