Where did that pic of the greyscale version come from, and are there any more? Thanks!
As for the ongoing color debate, we've established that it's all over the place in the books. Blue...grey....black. As for which one is "right" it's obviously subjective, but like I said before, I lean towards BLUE with the yellow oval which is obvious....and BLACK once the yellow oval is removed. It just fits thematically, despite the occasional panel with a blue cowl and cape.
Besides, the DC Direct toy, the Mattel toy, the Kotbukiya statue all used BLACK cape and cowl for the all black bat symbol, so in my mind that's the "official" color and the dark blue/black bat is just a variant.
But hey...factor in which ones are easiest to get, which ones have which accessories, and really it's up to the individual.
I just went ahead and pre-ordered them all. And I'm gonna try to get that black and white one too, cause there are also scenes which are close to B+W in the comic. Besides I think it looks doooooope. And don't forget, DC Comics continues to milk every last penny they can get out of their five or six "classic" books: they are releasing a hardcover of DKR in May in all black and white.
(....and I'll end up buying it anyway. I have no will power when it comes to this book.)
