"We have wanted to create a new installment in this series for a number of years," commented the title's original executive producer, Keiji Inafune. "And it is great that we now have the opportunity to bring this title to the Nintendo 3DS."

Mega Man Legends 3: Prototype Version
Mega Man Legends 3: Prototype Version, known (roughly) as "Rockman DASH 3: The Prologue! Showing you the Game's Underbelly Version" (ロックマンDASH3 THE プロローグ! ゲームのウラ側見せちゃいます編) in Japan, was an early version of the game that would be available for download in the Nintendo 3DS's eShop. The prototype would have feature playable segments as Barrett and 10 missions. It was originally planned to be available upon the launch of the 3DS eShop on June 6, but it was delayed to be improved. Initially it has been said by Capcom that if the Mega Man Legends 3 Prototype Version does not do well upon its release in the eShop, Mega Man Legends 3 may be cancelled, but the Prototype Version has been cancelled along with the main game.

Cancellation
On July 18th 2011, a message has been posted in the Devroom announcing the discontinuation of the project. The reason for the cancellation was that "it was not felt that the Mega Man Legends 3 Project met the required criteria".

Trivia

 * Some years before Mega Man Legends 3's actual announcement, Hideki made a post in the Rockman DASH series official site announcing the development of the games "Rockman DASH 3: Episode 1" and "Rockman DASH 3: Episode 2 - Revival! The Dark Lord of the Ruined Country" (「ロックマンDASH3」エピソード2～復活！亡国の冥王～). His post was shortly edited by another person to say to not believe him as he was drunk, being only a joke.
