Quantum Theory and Trinity Zill O’ll Zero didn’t have set release dates in the West, but time at which they arrive here will probably be effected by the fact that both titles are missing their March release dates in Japan.
Tecmo Koei decided to delay the titles to improve their quality before release. Now both titles are listed simply as “TBA.”
As of right now in North America and Europe Quantum Theory has a Spring 2010 window and Trinity is just listed as 2010. Depending on how long the titles get delayed, they could still make these windows in other regions.
