found this on evo m, looks like the 4G63 will be put to rest after the 2006 IX SE models, in the evo X they will be using a 4B11T motor and the lancer will be a 4B11 non turbo motor. dont know if its going to be the same here in the states, but heres a link for the 4B11

This may also be relevent... This engine may be the same engine intended to go into the 2008 Caliber and other Chrysler cars (Turbo 4, SRT4)
