It says the X is due for a facelift in 2009 or 2010. No info has been leaked yet.

The Maxima is schedule to be redone in '09 as well as possibly the 350Z and they are supposedly debuting a "Cube" to compete with Scion.

Let's just keep our fingers crossed that the X doesn't follow the trend of the Pathfinder and go from offroad-worthy to urban crawler.
