Prestige 99 to 100. Will my weapon progression be reset one last time or does it stay?

Hey everyone,

I am currently prestige 99 lvl 24 so my climb to 100 is finally over in a short amount of time. As I would like to start unlocking every weapon variant etc. I was wondering if my progression will be reset one more time when hitting prestige 100 or am I already in the last round of having to unlock everything?

Thanks in advance!
