Not sure if you are aware or are following the discussion about the design flaw in BTC - where it loops and issues a whole new batch when it reaches the "final" block see http://www.rimbit.com/threads/coindesk-replies-to-the-bitcoin-issue-they-never-followed-it-up.2398/#post-5032.
 

The theory is that this is a problem but will not happen until 2125 so lets make ourselves loads of money and who cares about our children/grandkids.
