With the release of zbrush 4r7, KeyshotHD will be $350, with an intro price of $250. It's exactly the same as the $995 version of KeyshotHD, the only difference is that it is speficially for zbrush. This comes directly from the zbrush forum announcement of zbrush 4r7, due to release this fall (along with the free beta of zbrush 64-bit). That's even cheaper than Poser Pro. 

The reason this is relevant to Poser users is because of Poser's GoZ functionality.

(Of course, there's no specific date announced yet, just "sometime this fall - which could be Dec 20th, lol. But the idea of 64-bit zb is what I'm most interested in, along with the new poly modeling features. I can only imagine what kind of awesomesauce that's going to be like. Nerdgasm galore!)
