Vintage Characters?

Is the Prophet of Regret, the Old Arbiter, and Forge playable online via in game ‘unlockables,’ or will they be a part of some sort of downloadable content to be released?

You can get forge now by searching in the xbox store.

When did they announce arbiter and the prophet?

Are the old Arbiter and Prophet of Regret are confirmed or what? By the way I just got Forge on the link thanks. Here’s the link.
