This whole policing of a discussion is sorta unnecessary if you were to ask me - and nobody did, so take my words with a grain of salt.

But that's the nature of communication. It's malleable; good conversation should be fluid enough to allow for off-topic discussions whilst waiting on updated information.

With that said... just allow things to progress as it has is my recommendation. Sure, it's off-topic, but once announcements happen, it'll be back on track soon thereafter.
