The publisher for the recent European version of BlazBlue: Calamity Trigger recently announced plans to release the PlayStation Portable and PC ports in Europe.
The PSP version is the same BlazBlue Portable that was released in North America back in March, and the PC version is essentially exactly the same as the console versions. PC owners will also be able to play Xbox 360 owners through Xbox Live, which can be accessed on PC. No announcement on a PC release in NA, however.
No exact release date has been confirmed, but the duo are expected sometime around June/July.
