P4 still. Skipped P5, but have yearned for dynamic clothing and more realistic hair, so, since no one in this typically hyper-critical crowd has seriously dumped on it yet, and the new features do all sound pretty interesting, especially (for me) the lights and materials, I'll be ordering P6 this week. [Note to CL Marketing Dept: Mec4D's recent posts have probably had the most impact on getting one of your most parsimonious customers to actually pull out the credit card for this version.]
