Steel cents on the way?

I first read about this in COINage magazine (February 2008 issue): legislation has been introduced to change the 1-cent coin from copper-plated zinc to a steel composition that is treated to "impart a copper color to the appearance of the coins so that the appearance is similar to cent coins produced of a copper-zinc alloy". I haven't seen anything about it online, but the bill is H.R. 4036 (pdf). It makes sure not to affect the bicentennial coins for 2009, but this is a long-overdue change.
