It probably will be now. Samsung was working on getting one ui 5.0 to all eligible devices by the end of the year that's what's been holding security updates back, my s22 ultra and s21 never got the December patch until just last week.
I'm currently on one ui 5 and android 13. I have an a53. I haven't got the December update as well, so likely for it to be stronger security when they release it in January.
