Heh, the comments you quoted were directed at the 4.4L. /ubbthreads/images/graemlins/wink.gif CARB doesn't want any more diesels, period, and even if the mfg'ers can make a diesel as clean as a gasser, the diagnostics requirements for vehicles under 8600lb are tremendous.
In fact, if I were a betting man, I'd wager that less than 25% of all the "announced" diesels you see as possibilities for '09 or '10 will never see the light of day. Heck, even VW is having a bunch of trouble getting the TDI ready for next year, and they have more LD diesel experience than anyone!
