I don't think car CD players will be eliminated anytime soon. Lots of people have lots of CDs, and it'll be a long while before everybody's ripped their entire music collection onto an iPod or equivalent. You still need a radio (satellite or standard) and a place to plug your iPod into. Adding a CD player to that costs car companies next to nothing.
