I'm assuming not, but I think the Xbox does support IPv6 now, so if you're doing dual-stack, that would hopefully take care of that issue to some extent, anyway.
I don't think that the xbox NAT issues are nearly as bad as they used to be anyway... I haven't heard from any of our customers complaining about it in a long time, and since we have our SM's all in NAT mode, there should still be a lot of people that aren't getting things forwarded properly (even with uPNP running on everything).
