Hi Jez
I don't have any information about 64bit windows but I expect that it will be OK (based on the fact that I didn't see any reports of problems specific to the 64 bit version).
At the moment I am working on getting projects ready for CW10. Since this is the direction that various IDEs are moving in it seems to be a necessary move, although I also would prefer to avoid it. Eclipse based IDEs have proven to be the biggest single drain on time and energy in the last several months. They do work, even if rather over-complicated and slow, but the biggest problem that I still haven't solved is how to manage a number of different projects (different processors and different applications plus different eclipse based IDEs [AVR32 studio, Atollic, CW10, etc.] when each one seems to insist on having an Eclipse type project in its own environment... but I haven't given up just yet...
There will be a Kinetis port make avilable quite soon (maybe end of month) which will (if all goes well) contain projects for CW10.1, Keil uVision4, IAR6, Rowley Crossworks V2.1 and GCC stand-alone. As you see, there are various alternatives depending on preferences, whereby CW10.1 is the only Eclipse based on. I too am wondering whether this option will prove popular. The K60 Tower will be supported, together with TWR-SER and TWR-LCD boards.
Regards
Mark
