I doubt the first boards will have NF200. You've seen the current uniprocessor Nehalem boards, they're all based on the reference design dug up by HKEPC apart from Intel's own - they're not going to go ahead and rip that apart just for some dumb SLI tax chips. If a company does that I'd say they're destined to get buggy boards and a crappy reputation.. It's not a board I'd want, change up the design two months before release? No thank you.

I think the first ones will be the basic Tylersburg 36S reference board they all have currently, no silly green chips at first.
