In September 2012, Tekken producer Katsuhiro Harada proposed for the game's ocalization. The localized versions will have Japanese voice overs and English subtitles.
The game was developed by Xenoblade developer Monolith Soft together with Banpresto who is known for their Super Robot Wars game (from which Project X Zone seem to take some inspiration).
Project X Zone features over 50 characters from different game franchises published by Namco Bandai, Capcom and Sega. The game will be released sometime this summer.
