Quite possibly the biggest piece of news at E3 was the unveiling of the Nintendo 3DS. The system's announcement included a bevy of new titles from both first and third parties. Lots of tech demos showing off the device's capabilities were out to play on the showroom floor, too, including a '3D enhanced' Mega Man 2. An eye witness account of the demo from IGN below:
"One of the more surprising of the tech demos was something called "Classic Games." In this interactive but nonplayable demo, you could cycle through 18 different pixel-perfect NES and Super NES games and see them reprocessed in 3D. Basically, all the sprites and backgrounds have been pulled forward or pushed backwards to provide the appropriate illusion of depth using the stereoscopic LCD of the system.
"The list of games in this collection included Mario Bros., Tennis, Super Mario Bros. The Legend of Zelda, Metroid, Musasame, Punch-Out!!, Excitebike, NES Open Golf, Twin Bee, Super Mario World, Kirby's Adventure, Mega Man 2, Castlevania, Urban Champ, Kid Icarus, Yoshi's Island, and Smash Ping Pong."
No footage of the demo exists at this time, but it shouldn't be too hard to imagine what Mega Man 2 in 3D would look like. Bear in mind, this is by no means a Mega Man game for the 3DS nor a confirmation of one; merely a technical demonstration.
