I attended the Arrow event in Chicago area (Itasca, IL). I had experienced similar delays. The Arrow rep. told me that Freescale expected a 50-50 split in demand for the K40 and K60 kits, but the actual demand was more like 20-80, higher demand for the K60. So they are trying to catch up.
The instructor offered to let me have his (classroom demo) K60 which I accepted - works great for me.
