They don't do release dates and unfortunately we don't know what exactly is coming out with Version 1.6.0. We know 1.6 is to focus on Ranked changes and the 1.6 series will add new roles, but that might still be many months away.

I haven't heard anything about removing Elo at all. Currently they're taking feedback to see if players think the Elo distribution is inaccurate. If you're a Ranked player, be sure to leave feedback in there. (Go ahead and vote in the poll, but also actually type something up if you're serious.)

So far, I get that vibe that:
 * 1.6.0 will not be bringing in new roles
 * 1.6.0 will not reset Elo and that likely won't happen until further along 1.6 when they are ready to begin Ranked seasons
