I've read anecdotal numbers as low as 5 years, and marketing claims are always huge (100 years!), but most of what I see is about the lifespan is when the flash is actively used (so running out of read/write cycles), rather than the on-the-shelf lifespan of already written data. The few numbers I've seen at manufacturers websites about retention specifically, suggest it's around 10 years (depending on how well the flash is stored - heat makes it die quicker, etc).
