Very bad news concerning the status of Mega Man Legends 3 on the 3DS as Capcom dropped the game and all related news on the game from their website.
The same thing occurred with Mega Man Universe before Capcom officially pulled the plug on the project.
The project itself was on very shaky grounds due to the creator of Mega Man having to plead with the company to even have the project be given a "prototype" status due to Capcom's bosses not wanting to spend any time on a new MML game.
Once Inafune left the company, Capcom began to start the delays and eventual removal of the promised June demo from the 3DS eShop.
