“Tomorrow at @pnwr.yoyo we fully release the Summit 2: First Draft. This only differs from final production in the Side Effect art and body color, neither of which will be produced again for this model.”
As JT said, the engraving on the First Draft’s Side Effect is much thinner than the production one—it’s not the same engraving (presumably because it’s a first draft of the final engraving, ha-ha).
Apparently, the production of the Ultra State is unique in that it requires Shawn to stand over the machine the entire time and determine by listening to the sound for signs that something is going awry.
Edit to add: I got the impression that it is the next release after Summit 2.
