Obviously, we are going to see new iPods, but I’m going out on a limb and think the Classic form might be retired in favor of the Touch model. The Touch will go to 64g. New Nanos with a larger screen too.
I also think we’ll see a new iLife with improvements to Garageband. I’m 50/50 on a new iWork; a part of me thinks we’ll see that at Macworld, but since the 08 version got rolled out at last September’s showcase, it wouldn’t surprise me if we saw an update today.
What I’m hoping for is firmware 2.1 for the iPhone.
