FWIW, Star 94 is the 4th oldest moniker on the commercial FM band in Atlanta, behind V-103 (1977), Kicks (1981), and B98.5 (1985). It's been around since 1989. It could be a refresh if they try to stay with CHR/Hot AC.
Star 94, and its predecessor 94Q, has always seemed to struggle to find its niche and identity since breaking away from Quixie, playing around with smooth jazz, AC, hot AC, and CHR/M (and a stint with a CHR/AOR "Rock 40" hybrid in the 1970s didn't help matters). When Power 99 flipped to 99X in 1992, Star 94 became the closest thing to a CHR in ATL strictly by default. B98.5, Q100, and Power 96 all have much clearer identities. B98.5 evolved from soft AC to mainstream/hot AC over the years, but that's about it.
Peach 94.9 was still saddled with its BM/EZ heritage long after they flipped to AC, which was one of the reasons CC changed it to "Lite".
Of course, you could also argue that 4 full-power stations chasing after the same bucket of listeners, with music mixes more alike than not, is too many. And The Fish also, ahem, fishes in that same pond.
