Generally natural and butterscotch Teles are ash, but I just looked on Musician's Friend and they've got a sunburst Tele Deluxe that looks like alder, and they've also got a listing for Telecaster American Deluxe Ash Series, which costs $100 more, so it looks like that's the only way to get an ash body on an American Deluxe. The regular American Deluxe apparently doesn't come in natural or butterscotch this year.
As for previous years, I'm not sure, but like I said before, generally the natural and butterscotch have been ash bodies.
