Haha "Thank you, but no thank you!"
I would like to know the principal reason Capcom couldn't work it out with Legends 3; because seriously, from the footage shown the gameplay was pretty much already done and had a Metal Gear Solid 2/Kingdom Hearts 2-esque beginning, that and they even had the fan support it needed, they even accepted help from the fans to develop some aspects like the name of the new female character, the design of Rockman, a new boss.
Contradictory argument, maybe that's why they couldn't develop it further, they were dry of ideas... then what's the point of being a developer if you can't do it on your own!? Ahh Capcom, I would like to see you struggling for capital and resources because of your bad actions...
I would like it if the fans keep pushing Capcom and at least tell why they couldn't make the game.
