I know Batman Detective Comics (New52) have them out (1-7, 8-12, 13-18) but does anyone know if Legends of the Dark Knight is getting one (Issue 8 has just come out) - thinking of following my titles by the trade paperback collection route rather than the weekly individual comic route and saving ~50%.

I switched to trades a while ago, so much cheaper, having to wait is a pain but worth it I guess.
Is this the one you mean? http://www.amazon.co.uk/Batman-Legen...he+dark+knight

According to amazon it collects issues 1-5 and will be released on September 10th.

yup that be the one (yay!!) - am off to check that they tradepaperback the other titles I'm following, then I might just move to tradepaperbackville.
