At a fan event in Japan it was announced by BlazBlue
developers Arc System Works that there will be a second DLC pack unleashed for BlazBlue: Continuum Shift
which adds a new character to the title. That character would be the aforementioned Valkenhayn R. Hellsing.
No details on pricing or release dates were given, though if we use the previous added character Makoto as an example, it wouldn't be illogical to expect this round of DLC to cost 560MSP too.
