Quoted from PinballManiac40:Lyman identified some issues with the code during tournament play. I can imagine that will turn into at least a bug fix release.
There are a LOT of bugs in ST ... I'm sure some of them will eventually be fixed, and maybe a spit and polish to the rules and code generally. But it's 18 months since the last release, and supposedly there will be a final release for AC/DC too ... but that's been 2 and a half years now.
So who knows when it might actually happen. Could be 5 years.
