There was a huge update to bmrf.us, which is owned by Josh Hubi AKA Hubicorn, which is one of the BMS developers.
Some transmission stuff with a lambda commented out in the source, much like the BMS Homepage, this leads me to believe it’s fun decipher time again, and probably extremely close to the launch of BM:S on Steam.
Or… Hubi could be having some fun.
Edit: IP appears to be the same as the one for blackmesasource.com.
