News: Nokia Camera = Lumia Camera Classic (updated)

It's obvious the update to Lumia Camera is imminent. Microsoft just changed the application Nokia Camera to "Lumia Camera Classic". There is no visible change so far though: no Rich Capture (read here), no 4K video. I understand Denim will be rolling out this month for the Lumia 930 and 1520, but I really hope to see the official update to Lumia Camera on the Lumia 830 sooner than that. But it just became even more confusing. I just downloaded "Lumia Camera" on the review sample I have from the Lumia 735. Still without Rich Capture (or 4K) - and I'm not sure it will ever be able to support that. So what's this all about? I'm confused. Any ideas?
