I was there yesterday and will be there today. Last year was a very different. The registration was in a separate area, which made it very dramatic when you first stepped in, as the exhibitor's booths were right in front of your face. This year, the registration was in the place of Xerox and Canon(they were pushed back just a bit) and then after you walked in, Xerox seemed to have several "buffer" zones. Once you got to the Versant, which was impressive, there was a very large open space and then the iGen, 1000 and CiPres were spread out. The J75 was actually in Duplo's booth which was down the line a bit. The layout this year at the entrance was underwhelming.
Ryobi did have a 5 color press which they had running. I'm guessing most companies don't want to pay for the personnel to run the machine, all the supplies, and transporting the machine, PLUS selling it at a heavily discounted rate. I don't know how many they sell due to the display, but I'm guessing it just wasn't worth it anymore because the 4+ color press market is seemingly saturated with machines currently.
