I was hoping the keyclone thing wouldnt require any waiting
When I went through the same process, including a full format, there was no waiting.

I just installed KC before I installed *anything* else at all, and PM'd Keyclone with my new system ID immediately.

By the time I'd got the entire system into a state that vaguely resembled a usable machine with the various apps I've come to depend upon (~2 hours - it's amazing how much crap I always forget about and have to re-download!), the licence had been transferred

Good luck with everything. So long as you have 64bit driver support for all of your devices, it'll be a breeze.
