Follow up to Cox notice

I recently posted a question about an equipment update from COX. A moderator, DannyS replied that the update involved new Tuning Adaptors.  Strangely, DannyS disabled replies, so I'll start another thread with my follow up questions.

1. As stated in the original post, my tuning adaptors were updated about a year ago.  Are you really going to update them again or is this an error.
2. I finally got a hold of a real person at Cox.  She stated that the update involves new Cable Card, not Tuning Adaptors.  She seemed to know what she was doing and was fully aware of the fact I had new tuning adaptors. She has send me two now cable cards.  So...  What's really going on?

Thanks,
