The next instalment in the White Knight Chronicles RPG series will be a PlayStation Portable-exclusive prequel, according to Famitsu.

White Knight Chronicles: Episode Portable Dogma Wars is due out in 2011 and takes place 10,000 years before the events of WKC and its sequel.

According to a Kotaku translation, it will focus on the making of the knights and the White Knight will be an adversary.

The Level-5-developed White Knight Chronicles began life on PlayStation 3 - the first instalment finally hit Europe earlier this year and picked up solid reviews in its revised International Edition.

White Knight Chronicles 2 was released in Japan, also for PS3, in July this year.
