I'd say he's more than likely just having a break. From the interviews i've read/seen he's a real spiritual character, If I remember rightly from an interview a few years back he ain't got much love for this world we live in & rightly so. No doubt he's over the scene & trying to find some perspective. But there's also a high chance that we may not hear from him again, I wouldn't be surprised if he's happy with what he's achieved in dnb & doesn't see much room to improve on his past achievements, so he's moved on to something new.
