"For the moment, no plans for a Western release."
And just like that, an English release of OSS is swiftly denied. While it's by no means a dead end (plans do change here and there), it's still unfortunate.
What can you do about this? Well, there's always Capcom's new suggestion box, wherein you could kindly request OSS to be released and translated outside of Japan, or you could wait patiently for an inevitable fan-translation patch to surface, which I'm sure isn't too far off...
Many thanks to Jimb0 for the heads up!
