So...

Amazon.co.jp released it 2 days early so it can arrive to me at the street date, which is appreciated.

I looked into the booklet real quick, and it seems like pure, 100% pandering. They introduce a new character, a strange maid (her blurb says "ちょっと変"). I sort of hoped for a 2040 reunion, but it is not on cards, apparently. Oh well. I did my duty to support the industry, and the main show was terrific.
