I am watching closely who will come to the Celebration Europe, although I think that the more interesting guests will come to The Celebration in America.
I also suspect that the guests are a little less "accessible" than the conventions in the Netherlands.
The conventions in the Netherlands are much smaller and guests are mixing much more with the visitors. I even had coffee a few times with Jeremy Bulloch and dinner with David Prowse among others. At one point I even drank a lot of beer till 5 in the morning with the Matrix Twins and Lawrence Makoare (Lurtz in LOTR). I think those things aren't even remotely possible on conventions like Celebration.

We'll see.............
