Mmmm, my personal view on this:
Mentioning again the priority list:
a) Classic (1971-1985-ísh) video arcade games
b) Pinballs (any era)
c) everything else The reason also for this is that there are already lots of homecomputer/classic console meetings throughout Europe. Again, not ruling them out, but we'll have to consider...
I'm not a big fan of PCB's being swapped around constantly in my Jamma cab. Also there's a PC in there now in the place where usually the boards are installed.
Also, it's not a big secret that I'm not a fan of the generic Japanese cabs and the games that came with them. I also completely do not see them as classic (again, the era 1971-1985). Please, let's not have a discussion about if they are or are not...it's just what I feel about them.
So my _personal_ preference is that I reserve as much space as possible for the "priority list". You see, where do we draw the line ? First it was plastic cabs with Jamma, but now there's talk of XBOX 360, sorry but the goal is CLASSIC games.
Again, not trying to spoil anyone's fun here, but I do try to keep things focussed.
So, not ruling them out completely, but the priority lists still stands.
Regarding point c) in that list, I think focus should still be on classic machines (IF there's room for them, so Atari 8 bit, 2600, C64 etc.) then on modern day XBOX360/Wii etc. gaming, I think there's plenty of that going round and everyone can play it somewhere.
P.S. this also follows CAX (which was the inspiration for Eurocade), no plastic there either.....
