Apple traditionally updates their iPods around this time of year, and I suspect that Apple’s event scheduled for 9/9 will be no exception. This is what I expect we’ll see:

• New iPod Touch: This will be the most iPhone-like iPod to date, adding a camera and a microphone. I expect we’ll see a video-capable microphone. Essentially, it will be an iPhone without cellular connectivity. This model should also have the faster processor used by the 3GS. I don’t think we’ll see an OLED screen this year. It’s reasonably likely that the high-end model will have 32 GB capacity.
• New iPod Nano: We’ll see a switch to a widescreen format to mimic the display of the iPod Touch/iPhone. I don’t think it will be a touchscreen model – the clickwheel will be retained. Expect to see a camera added, but I wouldn’t be surprised to see the Nano have still-only capability (no video). I also expect a low-end model that will essentially replace the shuffle, perhaps without a camera.

The future of the Classic is a little less clear. Flash memory is still not cheap enough to allow for the >100 GB capacity of the Classic model, so I think it will probably stick around for another year.

The Shuffle has less of a purpose and I expect to see it disappear.

The rumored iPad/Tablet will not make an appearance.

I don’t think Steve Jobs will be on stage for this one.
