Quoted from BrewNinja:
I talked to Scott for a long time when I stopped to pinball life a month or so ago. I was nerding it up with him for a long time, and asked a few general questions about game 2. I wont give anything away (because I don't know if he wanted the info shared or not), but he has something new up his sleeve for us (kind of like how the Danesi lock was new at the time) He did say that there will probably be no game 3 from him. I'm really looking forward to see what he has in store for us.
Me too, and I also respect Scott too much to reveal anything (plus what he showed me could change drastically by the time it's revealed anyway). But yes, he does have some things up his sleeve. There COULD be a game 3, but he's taking a long break after this one (and well deserved).
