Archiving on Blue-ray.. what are the issues that people are afraid of..?

Question

I'm considering how my latest storage monster toy (Hi definition camcorder) is going to eat disk space and realise that very very soon I'm going to want to move archived projects onto some external media that isn't going to consume that spare room in my house.
I dislike the idea of using a ton of external USB disks for the reasons above and the environmental factors associated with those disks and tape drives.. well it gets kinda expensive real quick when you start to look at current models and limited lifecycles that tape drives have before they need replacing.
My thoughts are that Blue-Ray is the sweet spot at the moment but I have heard people on this forum saying that the life of the media is questionable and comparable to various DVD media types.
I did a little digging and found that Archive quality non-organic BD-Rs that use a SiCu substrate approximate the UDO disk format that is traditionally used by large organisations for archival storage.
The UDO format has a life of approximately 100 years and some BD-R vendors are certifying their media for ~50 years. (cost about £25 for dual layer 50Gb today).
The recording technology on the media is radically different to various recordable DVD technologies that typically use an organic dye that is subject to deterioriation over time.
My thoughts are that BD-R will see most consumers out until the next generation of technologies (Protein Coated Disks and Holographic Disks) start to become mainstream and in the meantime we have some significant advantages over the tape guys such as size, random access and costs (being driven down all the time by consumer uptake).
So, what have I missed? Are there additional factors or are people only nervous because of FUD..?
