The problem with an iWatch replacing all or part of the iPhone or iPod's functionality is how to get audio to user's ear(s) in a non-awkward fashion. One option would be to add a bluetooth headset (probably stereo), but adding another device that needs to be charged regularly just so you can talk on the phone or listen to music isn't a great user experience. Another option would be for the iWatch itself to be a handset. It would have to be easily removable from your wrist with one hand (cf. http://www.halfbakery.com/idea/Slap_20Bracelet_20Cell_20Phone http://www.halfbakery.com/idea/Slap_20Bracelet_20Cell_20Phon..., though it could just as well be a bluetooth device). Music would have to use a different mode/device. When there's an incoming call the watch face shows the caller ID and to answer you, say, squeeze a couple of buttons on the side of the watch, and it unwraps itself from your wrist and turns into a little stick that you hold next to your head. A final option would be to embed the microphone in the watch band and have some kind of semi-detachable earpiece that you could hold in your hand/stick onto your finger and basically talk into your hand as though you were pantomiming holding a phone. But a device like that seems far to fussy for a company like Apple to put its product development efforts behind.
