Blizzard have announced that a couple of features found in the beta, Scrolls of Companion and Scrolls of Reforging, have been removed with the latest patch (10) of the beta and will not make it into the full game at launch.
"In both cases these are features we felt were underdeveloped and just not quite good enough for the game in their current state. The companion pets felt like they were mandatory to maximize play efficiency and some of the pets were too cutesy for the gritty, dark world of Sanctuary. Neither of those are issues we felt like we could solve without a lot of additional work, and we're trying to close in on a solid release date for the game, not move further away. When weighing these systems against releasing the game, we decided to cut these scrolls and stay on track for the game's release.
We think we can make companion pets into a much cooler system (both mechanically and visually), and evolve the reforging scrolls into a more meaningful system at some point in the future. For the time being, they will not be in the initial release of the game."
It's pretty much normal for feature to get removed at this point if they're not where the developer wants them to be, but the most interesting part of this is of course that it sounds like we might be getting a release date soon.
