Devs have been coy about there being no extra patches, only that 9.2 is the last "major" content for Shadowlands.
If we are not getting 10.0 this year (Wrath Classic may be the only 2022 release, even if 10.0 is announced) we may get a 9.2.5 to tide us over until the next year. What do you think we could get with it that would get people to sub?
