It's still primarily a "gaming" voicechat/messaging system, but the software is all there, it just needs expansion. I'd be surprised if some sort of enterprise-grade discord didn't come about.
I suspect they're hoping to get bought by someone like Twitch or Steam which have otherwise relatively rudimentary chat capabilities, but is squarely in the gaming space.
