The 3rd Omega Labyrinth game ended up getting announced last Sept, but I didn't see any mention of it yet so I figure I'd make a post.
First bit of good news is that in an interview one of the game produces hinted at a Western release. Exact quote being "Omega Labyrinth Z couldn’t be released in North America and Europe, but I don’t think there will be a problem for Life." so here is hoping.
You can check out the trailer here:

I've also included some screen grabs of the BE scene.
