Honestly, I'd wait a bit until Google clarifies if you should have your mobile site on a new domain or same domain.
Personally, it bugs me to see people not use useragent detection to serve up a new style sheet for a mobile site, as opposed to redirecting mobile users to a m.domain or .mobi site.
I don't see why that is necessary.
I suspect Google will be clarifying in the upcoming weeks.
