Roadmap

We are currently focusing on finish up a final set of features before releasing 1.0 stable. These features are:

Physically based renderer
Linux/Mac ports

Planned for Q2 2017 release

Following 1.0 release the focus will be on following features (in no specific order):

Sprites & 2D rendering
2D physics (Box2D integration)
2D animation (Sprite based at least, likely bones as well)
Mobile render API (likely Vulkan, possibly Metal for iOS)
Android/iOS/WP ports
High level networking (replication, RPCs)
Effects/Particle editor
Terrain system
Unified shading language
Visual GUI editor

And more to come after that:

Dynamic global illumination (+ other high fidelity graphical improvements)
Occlussion culling
AI (pathfinding, navmesh)
VR support
Cinematics editor
Visual shader editor
More specialized editor tools for 2D games
Script debugging
Level of detail
XBONE/PS4 ports
BSP brushes for level prototyping
Offline lightmapper
And more to be decided later...

Implementation times for each of those roughly ranges from 1-4 months.
