yeah i know about OBJ. but animation? 

Well in theory you could export an OBJ file for each frame and render each frame out individually then composite them together. It's better to render an image sequence than an animation anyway.
Although that would be a whole lot of extra work, obviously.

Not that that would be much worse than what they have right now. The scene exporters will export the animation, but as far as I can tell there's no way to use the target app's superior controls to adjust it any, aside from the camera and lighting. That is, you can't get at the rigging in a figure, can't adjust joint movement. You have to do that in Poser and save out the changed version, then import that into your host app. Which of course, removes all the better surface data you might have created. So while you free yourself from Poser's render engine, you're still limited to using its rigging.
