My quick synopsis of my 6 hrs there last night: once again, these are MY personal opinions, so don't get all bent out of shape if you don't agree.
Plenty of games available to play, and it seems like more "A" list games like Monster Bash(Pretty sure there were 2 there), Safecracker, Creature, and so on, available to play.
Houdini was a ton of fun to play, and I'm considering making the plunge. Well put together, and a ton of shots to make on it.
Star Wars, although it's my dream theme, is a pass because I'm not sure Stern could make a less interesting game if they tried. Completely disappointing. You can trumpet the "the game doesn't have to have a bunch of stuff on the playfield to be fun" call all you want, but at some point you have to take a step back and realize that there's no way Houdini/POTC2 and Star Wars should be anywhere near the same price.
I was surprised at how much fun Batman 66 was. Might be interested if they ever decide to update the code.
Pirates JJP looks fantastic, but when I watched the gameplay, I unfortunately felt like it'll feel like the Hobbit, which is also a beautiful looking machine, but plays too slow for my taste. That being said, the line was too long to play, so I might feel different when I get a chance to play it.

And lastly, a quick shout out for everyone who brings games to the Expo!!

My 2 cents...
