Now that my account's finally been activated, I can clear some things up about what's been going on.
Firstly, yes, that is in fact the old WKBD newsroom they've renovated -- they turned it into generic offices for the 20-year interim, so the transformation is frankly amazing.

This was the original newsroom set in 1989....

The offices in 2013 (seems that octagonal structure was added later, after they stopped using the newsroom as a set)...

and the new CBS News Detroit newsroom (the logo sign is actually in the same place as the "Ten O'Clock News" sign in first pic!)
As for why WKBD's news went downhill by the time it was axed, frankly Cox had the worst possible timing in selling 50 (if they hadn't more than likely they would've landed the CBS affiliation and kept the news department open). Paramount was apparently allergic to any kind of news investment -- they'd owned the Fox station in Philadelphia, WTXF-29 (the same station Shaina Humphries worked for, incidentally) and they were still using
typewriters under Paramount, only getting computerized once Fox bought them in 1995-96. 1998 alone saw Paramount/Viacom axe their news operations in Seattle and Tampa (Tampa was facing much the same situation as Detroit, facing off against a powerful CBS-turned-Fox station), trim their Sacramento news op to just a morning newscast, and additionally ax an outsourced newscast at their Boston station. It was only the WWJ deal that gave KBD's news extra time and it clearly wasn't enough -- the quality had simply degraded big time.
After that, with CBS's TV station unit under the incompetence of Peter Dunn and Richard Friend, even former and current employees of the duop have gone on the record on the WWJ/WKBD alumni Facebook page that Dunn was "hell-bent" on not having news in Detroit. While there may have been legitimate economic reasons (being the fourth and fifth stations in a three-station market), considering both got ousted for racist and sexist behavior on their parts (as well as buying a TV station on Long Island so they could
gain access to an exclusive country club), it obviously doesn't reflect well on their decision. First Forecast Mornings only happened because it was a "pet project" of the then-GM; as soon as he was gone and the ratings came in, there it went. But with Dunn and Friend now completely out of the picture, Adrienne Roark clearly realized that they had wasted so much, and using 50 and 62 as an experiment into a new newscast for the streaming age could work.
I'm reserving my verdict on if the newscast is good for when it debuts -- the supply chain issues have meant the endless delays, but as we sit on the cusp of a new year, we sit on the cusp of a new era -- one unencumbered by previous failures, and a hard-working, committed crew ready to turn some heads. I end this post on some more before-and-after pics.
