The one concrete thing claim it contains is that they're trying to get the next WoW expansion out in early 2022, which is very unlikely even as a goal. The normal length of a WoW content patch is 5-6 months and going shorter than that causes problems for the more casual raiders who need that long to beat each raid. 9.1 just came out and 9.2 is happening, so the earliest they'd even want to release the expansion for proper pacing would be May 2022.
