There has been a bill initiated to extend it permanently and President Obama has put it in his 2013 budget to extend it for another two years.
In 2007, it took 3 months to get it enacted. (See the dates on lower section)
In 2012, the introduction to make it permanent was 2 months ago and it hasn't moved forward at all.
(Not much in the way of dates down there)
The Federal Budget of 2013 was presented in February. It's supposed to get approved by 9/30/12. Rarely does it get approved on time. The 2012 budget was approved at the end of December 2011. The 2011 budget was approved IN APRIL of 2011 !!
You can follow the introduction of the bill on GovTrack.US and you can follow the budget approval in any news avenue you prefer....it's everywhere.....
