Because who wants to ruin people's anticipation? Scott Peterson is amazing. He's known about this for half a year and he hasn't spilled. And he's still not spilling. I think if I'd been in his position and Annie Wu started turning in pages that look like the promotional piece of the first cover DC's been showing around-- Peterson gives you yet another chance to absorb its cool into your system, thereby enriching your own, personal cool-- I would have wet my pants.
Seriously. I would have done it. I'm one of the all-time best secret-keepers ever invented, but I would have at least wet my pants like an over-excited kid hitting Disney World for the first time.
Now I honestly don't think Batgirl Beyond will be Cass Cain's triumphant return to the DC universe. There may be elements of her in the mix, but I have a feeling this will be a totally new character. And Batgirl Beyond won't make me forget Cass, who is my once and future Batgirl/Black Bat of choice and always will be. Still I'm more than a little enthused about a serious ass-kicking Batgirl. With art that looks like this.
What I can't figure out is if Batgirl Beyond is a stand-alone title or if it's just an issue or two or three of Batman Beyond. A lot of the news I've seen has been contradictory on that point. One report suggested it's a new title, another said it's a miniseries within Batman Beyond, DC officially calls it an "arc." Or has my reading comprehension regressed that much over the past few years?
