I contacted the SRAM dealer in the US, I was told to check back in the fall. I haven't seen the i-Motion 9 in Europe either: I called the SRAM dealer in Hungary, and they told me that they ordered a couple of the i9 hub gears in April, but then had to cancel because SRAM kept delaying delivery. They told me that since there is a minimum order quantity and the season is over, I shouldn't expect them before 2008 — they are not gonna order N of them to have N-1 sitting in storage until next spring.
Let's face it: the season is over, and the i-Motion 9 turned out to be vaporware. Nice job, SRAM, I am getting a Shimano Alfine.
