Well, here's my theory
By Summer 2007, there will be a set of 12GB Nanos 250 dollars American, making 8GB 200(down 50), 4GB 150(Down 50), and the 2GB 125(Down 25), and The 1GB Shuffle(with a sturdier clip) is $75(Down 5).
At Macworld on Tuesday, we will get the first brief glimpse at the 6th Generation(Maybe not..) Which would come out in Fall 07.
Here are my predicted Specs
Models: 30G, 60G, 90G
Price: $300, $350, $400
Other New Features: Dual Headphone Ports, bigger screen(But not Widescreen), I don't know ,i can't really think of anything.., other than definatly No Touch Screen. I'd like to see a wauy to watch videos and scan for stuff at the same time..
In addition to the new iPods, iTunes would have new features such as
-Movie Trailers now in the Movie Section
-Favorite artists(For example, lets say you have an album by Queen, and the soundtrack to the movie Spider-Man 2. So instead of scanning through all the titles to get to the queen songs, you can just go to that one quicker. This would be really useful since it takes me about 2min to get to Weird Al yankovic by Artist Section)
