There weren't many left when I got mine about 2 months back. Supplier told me they were going 650b for 2014.
Love mine though, running 150mm up front, the bike is so playful and gives great confidence, can still pedal it all day though. They are quite short but I'm 5'11 running a large with a 50mm stem and it's all good.
Got mine in lemon/lime and glad I did.
