Just to add my two cents...

Paganartist hit a bullseye. Poser 8 has to move into the 21st century by being a true 64 bit app - not just a 64 bit render engine. I can live with the slightly clunky library system. Heck, I have PzDB which makes content searches a dream. But the move-up to 64 bits is essential. The other two essentials are: control over lighting influence for each light, as in Vue Inf. and C4D (including specular influence), and two interface enhancements - a gizmo that lets you place objects in a scene more precisely (like the gizmo in Vue - where you can simply pull/push an arrow, instead of dialing dials!), and the ability to zoom in/out using the mousewheel. These improvements make it worth my $.
