Man. No love for the P-ROC showcase? It's going to be awesome.
The guys from Pinnovating are shipping over their Matrix pin, and bringing code for an alternate version of Demo Man they cooked up. Dutch Pinball's Bride of Pinbot 2.0 will be there. A fully custom game called "Wrath of Olympus" by Scott Gullicks which is turning out amazing will be there in some form. And more! Not to mention the whatever developments on the P^3 that Multimorphic decides to show off.
