First time home buyers credit

I am hearing different things about the first time home buyers credit.  Does anyone have an insight they'd like to share with the rest of us.  I've heard the next first time home buyer credit may be written for military home buyers only.  I sure support our troops and want them to have an opportunity to buy.  I am retired from the Navy and my wife and I have owned homes from the time we were 21 years of age.  What I wouldn't have done for a deal like our folks our being offer now.
