I'm James and I'm helping out with iZone. I used to play/develop on Graal for a while, before a ~2 year hiatus.
Good news, iZone isn't dead and is almost ready (~80%). We'll need help getting there but the project is definitely alive.
Even better news for some, PC Zone hasn't been forgotten either. Once iZone has been launched, we will then look at PC Zone.
If you have any questions, just ask.
