5 stars has always symbolised max rank at 0 prestige so it wouldn't surprise me if 55 is the highest rank for the first prestige.
Also there is the rumours of the highest rank changing after several prestiges?

It's only a beta so they probably wouldn't have had access to everything so it could still be the highest rank.
