On Facebook, Ryo recently replied to a fan asking if SB were disbanded and he replied saying that they were not.
AFAIK, Al is the only one not doing any sort of musical venture lately. Ryo just made an album and has been doing his Progject. Ted and Dave have been doing P-SA with Jimmy and John. And Nick is busy with BBT, among many other things. I'm not saying Al is the one holding them up, but the other guys have all been busy with other music.
At this rate, itl be at least five years since Noise Floor before a new album comes out, though they had planned a European tour earlier this year it didn't pan out for one reason or another. I still hope they have enough creative juices for one more album, but if not, they had a heck of a run - 13 albums over 24 years, a discography that all involved should be proud of.
