Virtual Height Field for Landscapes

I would like to know if this is gonna be the replacement for tessellation or how this is gonna work exactly for landscapes. I’ve watched some videos recently regarding having 2 landscapes meshes which sounds really odd to me as I can see clipping everywhere and the current texture streaming is quite bad. You have tons of issues related to clipping and low res textures visible when not in range or near camera frustum borders. Haven’t found a way to have a clean result and I know this is in development but in comparison to the other new technologies this is the worse implementation so far.

Question is, will it be a single mesh in the future and will we have some sort of collision or is this going to have that same issue as the older tessellation method?
