At E3 2010, a demo, "Metal Gear Solid 3D: Snake Eater – The Naked Sample", was shown on the Nintendo 3DS. The official E3 Kojima site later released screenshots and official art for the demo. Kojima did state, however, that this was not a preview for a full game but just a sample of what could be done on the 3DS hardware. Another mobile port of a previously released game was shown at Sony's PlayStation Meeting on January 27, 2011, where Hideo Kojima demonstrated a possible portable version of "Metal Gear Solid 4: Guns of the Patriots" for the upcoming PlayStation Vita.
