I don't expect that there will be any huge changes (though I guess we could argue over what constitutes a huge change....we've seen big changes in the last several years, but I don't think anything has been on the order of what the OP is talking about) To me their pattern seems to be big talk and then small actions - they prep people with sweeping statements like that and then the changes are relatively small. The reaction they seem to aim for is something like "Oh they don't want us to kill ourselves ala jonestown, they just want us to sell a kingdom hall and merge a few congregations, I was silly to have even worried about it."
The no-blood policy is even like this in a lot of ways - granted tens of thousands have died from it, but for most JWs it's a big ask that never actually comes to fruition. Then they're more likely to yield on smaller things since they've already implicitly yielded on something big (even if they never actually have to act in most cases).
The "adjust your thinking" type phrases have been around forever in the cult...that's standard cult fare - putting on the new personality, training your conscience, model yourself after Jesus (and the GB/CO/pioneers) etc etc.
