I've noticed this also. I've been monitoring a site for a couple of weeks now that has gained very high serp ranking and the site is only 4 months old. It has no content compared to my site and is ranking between positions 4-7 for several commonly used search terms. All I can put it down to is a change in the way Google see's keywords in the domain name... either that or it's Google giving a preference to "fresh meat" as I saw somebody call it last week.
