there have been loads of demos of the new software since Frankfurt and we featured it heavily on the UK roadshow too.

You don't have to install 4.2b from the website to use the USB stick (it is included). Audya 4, 5 and 8 users can upgrade without thinking, but 76 key audya owners must have installed the 2010 USB update (because of the huge wavetable changes).

The UK should have the updates ready to send by the end of next week, not sure about other countries.
