i think what we wish for next versions of sketchup stay just wishes and never seen by trimble, it is funny sketchup with many users doesn't have basic modeling tools such as quads,uv mapping, handling more polys, beautiful and organized interface and many other features. lack of these features always make me stronger for using other modeling tools like 3dsmax. i think using sketchup is not a serious tool for high end projects mostly for low amount of poly support and lack of high quaity ready 3d objects.
i wish companies like the foundry buy sketchup from trimble and make it super 3d modeling software but i think this will never happen!
sorry for poor english
