The max day will be extended to 80 in v0.60, so not the next update but the one after that :)
If that's the case:
v0.59 will be a smaller update than usual. It will add an outfit for each character that you can buy in the store, and then take pics of them wearing. It will hopefully also contain a side event scene, probably the second morning telly with Ashley and Hannah.
The reason it will be a smaller update is because I'm simultaneously working on v0.60. I'm not ready to announce all my plans for that yet, but the main thing will be the max day extension, and the day 60 exam and house party!
