CGI Block used in 2010 Maxx Force 7 (6.4L) on High way diesel engine

[scagmanf350]

I was reading in Diesel Power and Diesel World magazine about International's newly upgraded MaxxForce 7 (which is the 6.4L Powerstoke currently used Ford Super-Duty Models) an on highway diesel engine for commerical trucks. The new engine contains a CGI block (like the newly introduced in-house Ford production Project Scorpion Diesel Motor will come equipped with in late 2010). Apparently International has claimed the new engine block not only adds strength and lighter weight to the motor but it also helps with 2010 emission requirements. Since the new engine block is stronger than the previous generation it can handle high fuel pressure and combustion ratios making it the first heavy duty diesel engine to reach 2010 emission standards without the use of Urea Injection (Which the 2011 Scorpion motor will still use).
My question is will Ford be using this motor or is this strictly for commercial truck engines in 2010? Also if International can make emission requirements by replacing the block why can't the new Scorpion engine with out the use of Urea Injection? It may be too soon to talk about a motor slated to come out 11 months from now but anyone with any kind of insight is welcome to respond as I ponder this indefinitely.....
