When asked if EX Troopers would be released outside of Japan, Christian Svensson of Capcom responded:
No because EX Troopers isn’t part of the LP series officially (thus the difference in name) nor are there plans to bring it Westward at this time. Secondly DmC isn’t a sub-series. It’s an origin story.
He did say “at this time”, so maybe that’s a shred of hope you can hold to. But I’m thinking this will be something we’ll just have to live with forever. And that’s a shame.
