Well, the news here, Chrysler and Nissan have announced that it's best for both companies, to end collaboration, and therefore, kill all the deals they had. That means, the Armada and Titan are pretty much dead, until Nissan finds a new platform to base them on. Despite the Armada and Titan were somewhat successful, it seems that Chrysler, and its new Fiat owner, were the ones who demanded to end collaboration.
The collaboration involved:
1. Nissan providing to Chrysler a compact sedan for the South American market beginning this year.
2. Nissan providing to Chrysler a small vehicle for global markets beginning in 2010.
3. Chrysler providing to Nissan a full-size pickup truck starting in 2011.
