Engadget points to a couple of postings on the Notebook Review forums by someone who appears to be connected to Alienware. When someone said they'd like to see the notebook get the Optimus treatment, along with the option for Intel's newest CPUs and a better screen resolution, a poster named Darkhan responded and said everything but the improved screen resolution was coming. When pressed for a release date, Darkhan gave an end of June to mid July estimate.
Currently the 11.6-inch M11x ships with Intel's Core 2 Duo SU7300 (1.3GHz), Nvidia GT335M GPU, 4GB of DDR3 and a 160GB HDD.
