Query: Along with Wipeout HD, what game did the press view in 3D in early 2009?
Context: This was first demonstrated publicly on PS3 using Sony's own technology in January 2009 at the Consumer Electronics Show. Journalists were shown Wipeout HD and Gran Turismo 5 Prologue in 3D as a demonstration of how the technology might work if it is implemented in the future. Firmware update 3.30 officially allowed PS3 titles to be played in 3D, requiring a compatible display for use.
