Like anything of quality, if it is maintained properly, it will last. Rinsing the bladder out well with fresh water, and keeping sand and dirt off the parts is part of that process.
I have BCDs that have over 1000 dives on them. I have seen BCDs with issues with 50 dives. The better care you take, the longer it will last.
