we debated this; this is going to be a sequential rollout based on availability/capacity, and it seemed better to broadcast it was coming earlier b/c we're not going to have a "launch event" moment.
You could announce it when it's available to at least one user. "In the coming months" kills the excitement.
Arguably it would be good to not announce till it’s both available because even once released, expectations are going to be extremely high due to copilot.
So it's a soft opening. Like an out-of-town preview.
