I've no intention of changing my bike but I've recently started looking around due to having to price the bike up for the insurance company.
First I noticed that the 5 spot has gone. Okay, maybe I'll look at the burner.
But I really like the fox 36 fork.
But fox only do 650b in the 34.
Okay, another compromise.
Now, I can't see any 650b UST tyres, tubeless ready, but not UST.
What am I missing?
Looks like Schwalbe are the best bet:

Not that many 650b options generally yet, but Hans Dampf, Nobby Nic, Racing Ralph and Rocket Rons all have at least 1 650b/"Tubeless ready" option each...
I'm sure more options will turn up, it's not a massive leap for Maxxis/Continental/Schwalbe/etc to apply the same construction to another diameter, they're probably waiting a little to see if the 650b size really does take off, or if they'll only need to produce a couple of variants in 650b to keep the early adopters happy.
Edit: looks like theres a High Roller II option also...
To be fair there aren't many UST tyres in 29er either. Only Maxxis that I have found.
I guess they will come along eventually. Tubeless ready is the way forward for the time being.
I think long term tubeless ready will win out but have you tried a non ust conti rubber queen tubeless? Not great.
A mates running his 650b hans dampfs tubeless with no problems.
The recent non UST Conti Rubber Queens I have seen have a lot more meat to them than the older ones. My latest pair fired up tubeless with none off the faff and liquid leaks at the sidewalls of my previous experience. I think Conti are making there tyres a little more robust and tubeless friendly (and heavier) 
That's good to know.
