I walked across the aisle to the HMS Industrial Networks booth. They are well known for their Anybus brand of connectivity products. Michael Volz showed their PROFINET module that has been updated to include PROFIenergy:
When I got the chance to wander into the adjacent hall on the last day, I found some interesting displays. WAGO was showing their PROFIsafe products and how they leverage the iPar server. (See my iPar server blog post for an explanation.)

Since many real world installations use both PROFIBUS and PROFINET, this will prove valuable. They have created an introductory video here. You can get a closer look next year at our 2011 one-day training classes where they will be exhibiting.
The Balluff booth was a treasure trove of IO-Link products. Here is a wall of IO-Link products shown connected to PROFIBUS and PROFINET and other fieldbuses (IO-Link is fieldbus-neutral):
Two clever IO-Link products:
This short video starts a bit off-topic, but does show IO-Link:
