Here's a little preview of what you're currently waiting for:
Here's some images, one dragon with and one without SSS, and a lego technic car with some crude SSS materials.
We have fully working and VERY fast SSS ready for release in the next test version.
It renders about as fast (a tiny bit slower) as a glossy specular material.

And, it's unbiased/bruteforce SSS, eg no bias introducing photon grids or other precomputed approximations.
We also introduced various new nodes, including a medium node type and scattering function node type, that can be connected to materials to define the internal properties of media (eg BSSRDFs)
In the first release, we will have 2 medium node types, an absorption only node (but 3d texturable!), and an SSS node, with choice of phase functions. (single scattering only for now, but it's very practical and usefull already)
This is the prime new feature in the next test release, along with instancing support and FAST voxelisation, and another suprise feature,
aswell as the soon to be publically released first of a series of new products, OctaneRender for 3DS Max.
We hope this satisfies your long wait for a new version.
I can't give any timeframe, as you know me, it's never accurate and always later anyway

But it's definately weeks, not months
