Marcus To is currently on the Huntress mini-series and will be working with current Batwing writer Judd Winick.
The DC Blog The Source gives us a teaser as to what will come in that issue:
But To’s first issue finds Batwing still in Gotham City – unfamiliar ground for the hero of another continent. Having pursued Massacre to the United States, Batwing is faced with an even greater threat: The Court of Owls. It’s all part of the “Night of the Owls” crossover event coming in May.
