I'm just going to say so no one gets over excited. Sonic 4 isn't my priority at PAX East but, I'm probably going to play it since I'm there. I'm not going to go in and waste my day trying to get footage for it, since I'm only going there for 1 day. There are so many companies there, and I have about 8 hours to see them all, that's not a lot of time when you factor in waiting in lines. I'm just saying that I'll post some impressions about what I experience, explaining things enough of what people are interested in hopefully. Stage design, co-op (if applicable, I would assume it is), making sure the physics actually changed like the videos seem to hint, and whether the music still sounds like cats.
