It's only just come out, of course it'll take a while for the players to adopt it fully. Then you've got to update all your firmware on your devices to be compatible....it's a bit of work but the end result will be awesome I expect.
I wouldn’t be expecting much for six months to a year. So far it seems to be all over the shop.
Like all open protocols it won’t work as well as proprietary ones do inside their proprietary ecosystems but it will be much more flexible.
