There is a large presence of XPS at Winhec this year, which makes Global Graphics' booth banner very fitting:

Tomorrow, there will be several XPS related presentations (all in room 607/608), ask-the-expert session, and XPS printing hands-on-lab (room 617).
More importantly, there are quite a few people from Microsoft Digiital Document team who should be able to answer your questions about XPS.

XPS is here, you should be ready or busy getting ready.
