This isn't news as such as it was new in January 2009, but I just found it and thought it might be worth sharing
I discovered this forum thread on LucasForums that contain free movie style posters for classic video games such as Indiana Jones and the Fate of Atlantis, The Dig, Monkey Island, Day of the Tentacle, Maniac Mansion, Loom, Full Throttle and a few others.
Most images are 60x80cm @ 200dpi which gives something like 4724 x 6850 pixels. If I'm ever having a poster on my wall it will be one of these
