Well, there will be at least some new info to come out of this. It is an " extended" version of it
.
If I had to guess:
1) Explore more of the city within the demo
2) More info on the Battle system ( or at least more clear on what the battle system will be like)
3) Maybe Show the sleep in a hotel? XD
4) Perhaps a more define Battle screen? ( A better look into the UI?)
5) Possible Button Controls ( for the demo at least)
