Does anyone know if Poser 5 is DEFINATLY being produced? Is there any sort of time frame estimate yet? I am thinking about buying Poser 4, but at the price it is, I don't want to buy it and then find out 2 months later that version 5 came out (Or 2 days later either). Does anyone know for sure? Also if I do buy Poser 4, Is there usually an upgrade path for new versions or am I SOL?
