I also understand completely the idea of having a faster update, especially on a complex scene, and most especially if you could work real-time texture and lighting approximations into it. OpenGL seems a good choice for this, as it takes the burden off the processor...but ONLY if it is OPTIONAL. Making it the default is what I fear. As a reference; both Bryce and Carrara offer several different engines for workspace preview. My experience has been that the engine written by the same software engineers (aka, Eovia render) will work pretty good though sometimes slow, one of the other modes will have a few things it can do well (but everything else badly), and the third will lock up the program and crash my computer. Still, this seems a good direction for Poser. Parrellel "curious preview render" and OpenGL, with the user able to change on the fly. I do worry, though, with the small number of programmers they have they might just put all their effort into optimizing the latter and ignore or even remove the former.
