The <A HREF="http://usa.asus.com/products/mb/socketa/a7n8x-e-d/overview.htm" target="_new">ASUS A7N8X-E Deluxe</A> already has SATA and Gigabit LAN. However, these are operated through separate chips on the board. If you're talking about SATA/Gigabit LAN being integrated into the south bridge, I don't think that's going to happen. There was a rumored "MCP-S" with SATA support, but I don't think that south bridge ever saw production.
