There won't be a heavy duty Titan model in the short term. The HD model has been cancelled from what I've read. However, the 4L V8 diesel sourced from Navistar is still in the works. With GM and Ford adding small diesels to their 1/2 ton lineups the next year or two. Nissan has to offer a diesel option if they want to remain competitive.

The reports of the Titan being scrapped seem to be false. From a tooling cost perspective, it wouldn't make sense to drop the Titan while leaving the more profitable Armada/QX56 intact. The more models you have under the same platform increases profits by reducing overall development costs and shortens the time until amortization is achieved.

The next generation Titan will probably be just a reskin like the '09 F-150. The chassis structure will remain basically the same except for reskinned body panels and a slightly revised interior.
