It's 0.13.0.
I think PocketMine supports mobs but doesn't have an AI for them yet. Not sure when that will be added.
I've heard about that happening on older iPads on older iOS versions, but not newer. Hopefully if it's a newer device it's already been reported.
What iOS version are you on?
There's no way of telling right now.
We don't make Minecraft.
I don't think so.
Pocket Edition has the same textures file as PC edition, but this doesn't mean any of them are coming soon.
It's too early to make an accurate guess.
No, I think it still has a good chance for August.
