Why kill the Titan when you are going to be continuing to build the frame for a whole new series of vehicles?
Though the Titan is VERY long in the tooth, it still makes for a solid, inexpensive (when rebates are factored in) truck for many people and now Nissan is going to be using the basic underpinnings of the Titan for its new line of commercial vans to come out in the 4th quarter of 2010. To be similar, though not as fancy, as the concept shown above and displayed at auto shows last year, Nissan will still be able to turn a profit and keep the production line rolling with this new offering.
Likely designed to compete with the Dodge Sprinter and other commercial vans, this new line of Nissans will be welcome news to those owning Titans as they will continue to be made for the foreseeable future. Additionally, it may mean that Nissan upgrades the engine and drivetrain in the future while retaining the basic platform to keep a full size truck in their stable as it doesn't seem to make sense to totally kill the Titan while still producing its basic components for the commercial van.
