Yep, I already have a test version of 2018.
31 teams is a bit of a problem. I still haven't seen the 32-team rom, so I don't know if I'll be able to work with it if/when it's available.
If I CAN'T use it, I will release multiple versions of the 2018 rom with and without Vegas. Sorry, someone has to go unless the 32-team rom works!
