Well i will most certainly keep my copy of poser4, mainly because the new features of p5 will most definetly strain my computer so much that i wont be able to fully utilize them that often, if at all. i will endeavour to carry on with p4,as i also think that i have not exhausted its potential, its a personal thing i guess. one day when i have the money and have upgraded my pc somewhat.. i might go for p5.. til then its good ol p4 for me..
