I found this site about player ratings. The contributors have come with some in depth formulas. They have ratings available for 2007-08, 2008-09, 2009-10 and 2010-11 as well as a three year rating for 2007-10.
I am not sure if these ratings can be used in the new hockey game, but it makes for some interesting reading.
