I'm waiting for a Tim Sale coffee table book which has all of his Heroes art presented properly, both original black and white and coloured versions.

Either that, or, since that might not be enough for a full book, a good making-of Heroes book, which would include all his art - again, it needs to be presented properly.

Maybe Titan will do a Heroes book at some point - if they did one in the glossy format of their Firefly books, that'd be pretty awesome.
