RoS was near the top of Twitch for a few weeks when the beta first hit, but prior to that vanilla D3 hadn't been near the top for a long time. And once the Beta had been running for a while it kinda fell off again; I still think that they blew their load waaaaay too early with the Beta, I think at this point people are kind of tired of it, and based on some of the negative feedback people who haven't even touched it are coming away disinterested and with a negative opinion. I was super excited for RoS when the closed beta first hit, but after a month or so I'm pretty disinterested again. At this point if you're watching RoS streams you've probably long since most of the new stuff, and most people will only watch something that they can't play for so long before they get bored of it. I'll still pick it up day one, but I'm dropped my physical CE pre-order and just going digital regular edition. The tail on public beta stuff has been too long, I already feel bored with it and I haven't even played it.
