New SHG Glass?

So when can we expect to see them weather-sealed and significantly smaller m43 SHG 300mm f2.8, 150mm f2 and HG 250/300mm f4 or 150/200mm f2.8 glass? And while we're at it, how about a SHG 400mm f2.8?

If the EM-5's new fangled IBIS is all its made out to be, then we may be looking at the best hand-holdable rig for birding and wildlife
