I wouldn't expect anyone to say much right before Expo though, no point in giving away updates right before you have a seminar scheduled that people are going to pay attention to. Same goes for Dutch Pinball and JJP, it just makes sense.
Also, I'm totally not in charge of how Alien info is announced etc, but if I was Heighway right now I have to say that I'd focus on Full Throttle as much as possible. Show some Alien teases but talk about the shipping game. (This is me speaking personally, I have no clue what's coming on Thursday, I've been too busy working to even ask.)
It's kind of a big deal to have your first game finally shipping! Really proud of Andrew and the whole team. Obviously in this thread people want to hear Alien, everyone is curious, but Full Throttle deserves the spotlight for a bit.
