I'm not convinced that Bing pays as much attention to site age as Google. It has been mentioned quite a lot lately about people achieving good rank on fairly new or totally new sites. Personally I have seen brand new domains rank well within a matter of a couple of weeks.
I actually think this is a good way to go about it, age may indicate maturity, but it says very little regarding quality.
