We're expecting an announcement later today but the Alienware m15x has already been leaked in a trio of Dell service documents. Updates include a Core i7 processor, 15.6-inch 1920x1080 LED backlit display, a full 8GB of 1333MHz DDR3 memory, options for a traditional hard disk or SSD drive of unspecified capacity, a 2 megapixel webcam, Blu-ray disc option, Firewire, 3x USB, 1x eSATA, ExpressCard and 8-in-1 card reader slots, an optional 9-cell 86Wh battery, and DisplayPort and VGA outputs among other notables. It also features the same aggressive styling of its bigger dual-GPU M17x sib. What we don't see is any mention of its graphics. Will it be dual-GPU, too? Doubtful, but check in later to find out.
