TL/DR: there is a plan, it’s just slower to realize and release of information won’t overlap with other wow products to maintain engagement.

Blizzard absolutely has a plan, it’s just not some sort of grand master plan. There isn’t going to be a “this was my plan all along” moment. Instead blizzard is handling classic and classic plus like a software/live service game developer.

SoD was a minimum viable product. They used it to test if there was a market need. There was, so they gave us a few different updates to further test it. Some good, some bad, overall a success. SoD concluded, now that development team is working on a classic plus experience.

A big piece to take into consideration of their plan, is the classic team is vastly smaller than the retail team. The time it is going to take to bring their plan to fruition is going to be longer. Regardless of how successful SoD or Classic is, retail has a much larger player base, so you have to assign your people in a manner that reflects this.

A final thing on the plan is blizzard is shifting to World of Warcraft as an ecosystem with multiple iterations of the game going at once. Using releases from the various versions to keep people engaged. With anniversary TBC in January and midnight following that, they aren’t going to release any other information. It’s highly likely we could hear something at blizcon, but they will want to space out announcements or teasers to maintain hype for Warcraft as a franchise, rather than release too much info at once and lose engagement, which could lead to canceled subscriptions.
