2019 Ball Family Reserve Basses

I am very interested in ordering a BFR bass this year and was just wondering if anyone knows if a 5 string bass will be offered in 2019, since the last two BFR basses were 4 and 6 stringers.

Also, when does EBMM announce these instruments? Is it on a set date, or does it just happen periodically every so many months apart?

Thanks for your help!
