There have been problems associated with the DLC character Valkenhayn R. Hellsing and the general gameplay patch that goes alongside his release. The Xbox 360 release of the character and patch have been delayed, with ETA unknown. The patch for the Playstation 3 version also has issues as well.
OFFICIAL STATEMENT:
Arc has released an official statement, dealing with the issues causing this delay, and their suggested workaround. The issue is basically this: The patch that enables use of Valkenhayn (not the Valkenhayn DLC itself) also introduces a bug. Since the 360 patch and DLC haven't been released yet, the 360 version is currently unaffected, but any PS3 versions that have been patched are. Arc is, of course, currently working on a solution, but for now they have the following suggestion:

"Getting into a long-standing fighting game series is always a challenge for new players. There are so many characters and different versions to go over for many of them and going up against seasoned players who’ve been with the series for years is one of the biggest barriers. BlazBlue, however, has something a lot of other games don’t have; a ton of story. The series is known for having a lot of story content, which can make that initial barrier even harder for new players because if they jump into a new game and play the story mode, they aren’t going to be able to follow it." -- PlayStation Enthusiast

The 'visual novel' is a rather unknown videogame genre. Or is it? Professor Layton, Phoenix Wright and many other games are sneaking into the limelight by combining traditional visual novel storytelling with innovative gameplay elements. Do they have the potential to go mainstream?
Although I love them, I don't really consider pure visual novels like Higurashi or Umineko to be games... however I like that there are more and more games nowadays that use visual novel aesthetics as their story telling device

One version is enough for me. If they change everything I'll buy it.
