Bit too early for April Fools jokes, isn't it? No, this is not a joke, this project is cancelled. I don't see any reason to develop this further with another, strong editor as its opponent (plus, diegoisawesome is one of the greatest and most skilled programmers of his generation). Diego will shake this thing, I am pretty sure. So please do not worry about this and look forward to the "Awesome Map Editor"! :-)
