DC's top Bat-creators convened at Wonder Con last Friday (April 18, 2014) and asked once again if fans want to see Cass back in the funny books:
Next fan up to the microphone asked since Stephanie Brown is back in "Batman Eternal," is Cassandra Cain next? [DC talent relations director Larry] Ganem asked the crowd if they wanted to see Cass back, and received a fairly healthy applause. "Duly noted," Ganem responded. --Hit Fix
What this means probably has a lot to do with how you interpret the phrase "fairly healthy applause." The adverb suggests an audience response less than thunderous, but the adjective tells us it was more than feeble. Which part of that did Ganem "duly note?" I feel confident Cass will show up again in some capacity, at some point. Maybe a wildly enthusiastic response complete with a twenty minute chant of "We want Cass! We want Cass!" would have moved up the schedule for her reappearance, but one of these days, maybe even this year, DC people will start dropping hints and building anticipation.
The day that book hits the stands is when I next buy a new DC monthly. Not a moment before.
