The future value of KRL is in the Broker Reports
Decemeber 2009 Stonebridge suggested 55c as a 12 month target and the latest report from another firm quated 69c. If you look at the report 69c is valued with all of the projects up and running ie 2012-13.
I believe 55c will be the average by Decemeber 2010 maybe with some spickes into 60s. 2012-13 is too far to speculate but 69c would be a conservative estimate.
