Norton Internet Security 2009 Renewal

Maybe a dumb question,  but I just received a msg that I need to renew my subscription.   I'm running NIS 2009.    If I renew,  will I continue to run the 2009 version or will I have an option to upgrade to the 2010 version ?   I see in this forum that 2010 is still beta,  has it been released yet or is it still in beta,  if not,  is there a planned date for release and when it's released how would I upgrade ?  I assume there would be additional costs.    Ok so there were several questions.   Any help is greatly appreciated... Thx
