From reading AMD's website, it appears that all Tbirds will be released as Socket A. As I understand it from reading independent articles, there is extra manufacturing cost for doing SLOT-type processors without corresponding benefit on modern motherboards and die sizes. Most will be returning to a PGA. Pricewatch does not indicate any SLOT A Tbirds, not that that is the be all, end all answer. As always, YMMV. My crystal ball hasn't been all that reliable.
There's no justice, there's just us.
