I get it. I agree with you and I hope they do. I also want a brand new limited edition iPod Classic with clickwheel and everything.
But I think there's something that people don't realize. Why did Apple continue to sell the iPod Classic until 2014 when they already had the iPhone and the iPod touch? Because it was possible to cut costs and have a device with big storage capacity.
Let's suppose the iPod touch didn't exist. What would we probably asking for the iPod 20th anniversary edition? I guess probably something like the iPod touch, with internet connectivity, bluetooth, Apple Music, iOS apps, 256GB and so on.
My point is: I think that we take the iPod touch for granted. Besides its poor battery performance and lack of clickwheel, it is still a great iPod. It's got even the big storage. And we can buy that today for a very reasonable price I'd say.
You've probably seen this video from DankPods already, but it's worth to mention it because he shows this very well and I agree.
