Even if they are not meant to last, say, more than 10 years, you could back them up with fresh disks in 8-9 years timeframe and be good to go for another decade, What's important after is that the disk can still be read by newer drives later on.
No mention in the new release how long they are meant to last though. This seems like a pretty key point to me.
