Difficult to say since the media format hasn't been around for long.   
Accelerated aging tests of BD-RE say that it's good for 50 years.

The thing to be wary of is anything that uses organic dye layers for  
recording, such as CD-R and BD-RE LTH.  Organic dye media will rot  
(literally decompose) if air and moisture get under the polycarbonate  
sealing layer.  That includes scratches as well as the more obvious de- 
lamination.  If a CD-R lasts more than 5 years then count it  
fortunate, and I don't see BD-RE LTH as being any better since it's  
the same construction.
