But no, I don't the classic line will ever get an FM feature. The iPod touch still doesn't have one, nor does the iPhone (even though it already has the hardware chip built-in). Yeah, the Nano has one, but it's always been the oddball to the iPod lineup.
Probably not. The whole point of the classic is that the user loves music, has a lot of it, and likes to control it. At that point, the user has enough music to negate the need for a radio tuner. I can understand it on the nano/touch (if the touch ever got it) due to those devices having smaller space, because the radio could add more variety.
I think Apple's outlook is "why would you want to listen to radio when you have your whole music collection with you". I know I wouldn't, but I think that's the point. Not to mention, no one really walks around with a classic anymore. I only have one to serve as storage for all my music and videos that's linked to my SatNav system in my car.
