The only thing I have heard officially is the new SUT. I believe a late 04 model. H2 version of the Avalanche.
The only other rumors I've seen are simple things like possible Navigation System and XM Satellite Radio support. The XM one seems logical but I'm not sure GM has navigation available for any model.
Guess the other rumor is Diesel. Given the basis for the H2 platfrom is the Yukon XL and the diesel exists for that sure could be possible.
Would love to see XM in the 04s, now that I've had it I can hardly live without it. As far as the Diesel goes, it's a great engine, but from what I understand it is not available in the Suburban. Now I don't see why it's not, but from what I've heard GM is working on a "lightweight" diesel based on the Duramax for the Suburban (yukon XL)
