Nvidia will introduce a new south bridge called MCP–S where S stands for Serial ATA. Apart from Serial ATA this chipset will have the Nvidia Gigabit network adaptor which will be the last innovation for this new south bridge.

Boards based on this chipset will be released in the middle of July according to current schedule and will feature Dual LAN, one card being Gigabit capable while the other is 100 Mb LAN and of course Serial ATA will be part of these boards, and Firewire too, if manufacturers want that as well.
