No 64-bit variant this time, according to this report from The Register, a new core named "Appalbred" could make it to the market to replace current Durons.

[COLOR=royalblue]Appalbred will initially ship in three forms: 1400, 1600 and 1800, priced at $32, $39 and $47, respectively.

AMD's official price list contains just two desktop Durons, at 1.2GHz and 1.3GHz, priced at $39 and $44, respectively. If the Appalbred information is correct, it would indeed appear to be a Duron replacement - or at least a new core for the old brand.[/COLOR]

I'm not too sure if this makes much sense given the rest of AMD plans, what could be interesting would be AMD entering the low-power league to combat current and upcoming processors from Intel and Transmeta.
