The title of that talk was poorly chosen. It makes it sound today like an extremely premature announcement. Since then i chose to err on the side of silence 
But the project has grown non-stop.
It’s not news quite yet, but i’m hoping we can start showing previews by the end of the year.
In general terms, the main aspects of the next release are
- Modularity - open up and pick apart the Fluid Container
- Customization - build your own pieces for a simulation
- Tools for data types other than voxel grids.
TFD1 processes particles, meshes and textures on the CPU, only voxels go to the GPU. This is a major performance bottleneck. The new engine processes everything on the GPU and also provides tool sets to create and manipulate non-voxel data.
