What to expect next update:
A whole bunch of new Quests, CGs and events. It's a huge-ass city, gotta make good use of it.
Dates for Asha, Seras, Sonia, and of course, the CGs and H-scenes that come with it.
Some small changes to building interiors, mostly aesthetic and some for function (Like additional rooms)
Possible introduction of Gym Leaders 5 & 6. (You can't battle them yet, til the story progresses, sorry)
ETA: Depends on how smooth the beta testing goes. The problem with quests, is the off-chance that some of might be broken, or there will be issues and bugs caused by overlooked problems that we didn't catch on testing the events. There is a also a LOT of art CGs to do, more than any previous release. But I'm optimistic it will be out by the middle of June at the latest.
