Quoted from Pale_Purple:I'm going to guess finished animation and audio for the modes on the the phone and some more polish with the rules/scoring. Buffalo Pinball upload their streams to YT fairly fast right? Won't be able to watch it live tomorrow.
If the stream doesn't go up on YT (not all Buffalo streams do), the archive of all live streams is available here: https://www.twitch.tv/buffalopinball/videos . You can watch it any time after it has begun and see the whole thing
