Thinksecret is reporting Apple has run into technological difficulties and has delayed the release of it's true video iPod until the fourth quarter, but in time for Christmas.
Another factor playing in is the lack of cooperation with the movie industry in releasing movies for private owndership vs. a subscription-based model.
I have mixed feelings about the ol' 6G ipod. First, I bought my 5G ipod, what, four months ago? Honestly, a dely doesn't bother me too much. I'll get more mileage out of my current iPod before I sell it and get the new one.
