Patch translation post is updated.
I'm sure most of the players have realized this, but just in case someone doesn't know, looks like HK is currently revisiting old SR ranks. The first being the 00 7 Swords, and now Sazabi Mega Particle gun. No info on what old SR rank they'll put up next.
CMIIW about this one.
