I suspect that the heritage NBC stations (e.g., WNBC, KNBC, WMAQ, etc.) will keep the NBC# (or even "Channel #") branding. KNTV (NBC 3, NBC 11, NBC Bay Area...) hasn't been an NBC station all that long (only several years), rather than 50+ years...
KNBC still airs "The Channel 4 News" - and folks in southern California know that NBC is on channel 4 (regardless of physical channel number), just like folks in Utah know that ABC is on Channel 4 (even on analog with translators on different channel numbers). It's all branding.
Once the dust settles, you may see some requests to change virtual channel numbers (most likely to a lower number - maybe to match local cable systems?), but we'll let that scenario rear it's head off in the future...

You could be right - I haven't been in any other cities since the NBC changeover, so I can't comment. when KNTV first became an NBC affiliate (later an O&O), they branded as
"NBC3," (their Comcast Cable position), then went to
"NBC11" (broadcast dial position because they share some north Bay broadcast territory with KCRA - NCB3 in Sacramento. And the station is presumably in a different dial position if you have satellite, and different
still if you are watching them in HD.
All things considered, it just seems simpler to go with
"NBC Bay Area.".
This seems to be a trend -at least here in the San Francisco Bay Area - because our CW affiliate is now branding as
"CW Bay Area,", and independent station always known as
"TV20" has shrunk the "20" to a tiny font and is emphasizing their "KOFY" call letters (pronounced
"Coffee," naturally) as their brand. I expect the "20" to disappear at any time now...
