Intel is working on a new high-performance platform called Smackover. This platform will replace Skulltrail in Q4 2008:
It's name: Smackover. This server motherboard, rebranded as a halo desktop product, will only compete at the ultra-high-end enthusiast segment -- a market AMD recently exited.
Also like Skulltrail, Smackover is essentially a server motherboard with overclocking abilities for the upcoming Nehalem processor, also slated for release in Q4 2008. The board will use the Tylersburg server chipset with ICH10R.
Intel designates its product codenames off various points of interest on U.S. maps. Smackover, as it would happen, is actually a small town in Arkansas. It had to be somewhere I suppose.
