Your guess is as good as ours, but I think Youtuber Tips Out has a good vid focusing on this topic. He writes classic wow guides and has fresh some periodic game content. He addresses and surmises when we should expect to receive news about wow classic and when (if?) the alpha or beta for the game is coming. It’s all speculation of course but at least it’s a guess based on some research and uses precedent. So take a quick look.
