On the website of PDXLAN, a popular annual gaming LAN event, the organizers posted that NVIDIA and Gearbox Software are bringing something "really special", and that attendees are in for a treat that "will blow their mind" (sic). The more likely possibility is that the two unveil a new Gearbox title which is takes advantage of NVIDIA PhysX; the much-lesser likely possibility is that NVIDIA will demo this game on unannounced hardware. NVIDIA is known for unveiling new hardware to small crowds at gaming events such as these, and we wouldn't be surprised if NVIDIA does something similar.
