if ya already got poser 8, my vote would be to wait for poser 9.  they may start giving hints about the beta in march or april.  one of the advantages of pp 2010 over p8 is render GC, but:

• render gc 2.2 can be simulated with hsv exp tone mapping/gain (1.67, 1.33) in p8
• using bill's vss in poser 8, ya get the texture GCed anyway.
