New cummins diesel 5.0 L displacement (if it ever arrives)?

The 2009 Dodge Ram 1500 had a sticker that indicated two diesel displacements, 6.7L and 5.0L. I was puzzled by this. From several articles (see one here: New Cummins V6 and V8 Diesel Engines - Exclusive Preview - Diesel Power Magazine), Cummins had developed two prototype engines (a 4.2L V6 & a 5.6L V8) based on a 90 degree V. They were also going to use a slightly different block material, something called CGI (compacted graphite iron). I can't find the original article, but this is close (new 4.2 liter Cummins diesel coming to the Jeep line!!! - JeepForum.com). Its suppose to have better strength than cast iron and therefore the CGI engines could be made lighter. This material is also much harder and difficult to machine.

Is it a V8 and a V6? If its a V8, then did they change the material of the V8 from CGI and go back to cast iron and therefore reduced the displacement from 5.6L to 5.0L?
