Apparently the city's contract with JCDecaux for bus shelters and other street furniture will expire in 2022. The useful life of the bus shelters is only projected to 2030.
So the city is seeking new partnerships for street furniture that could include bus stop replacement. I actually don't hate the black-iron design of the JCDecaux shelters (done by Robert AM Stern, fyi) but wouldn't mind seeing something more contemporary. These things often bring out a high caliber of design as seen in NYC and SF.
