Just a quick note to say not only do I find T pose pretty much kills my ability to make clothes properly (since that's not their real world default state), that I don't model my clothes from T pose has been my key to proper shoulders in clothing.  Check out my Painted Sky for a small example of how nice and square and defined you can make jacket shoulders look when they're not modeled in the pose where they should be scrunched up and distorted.  IMHO, in the content community market, losing WalkDesigner support is a small price to pay for not having every piece of clothing not made by Uzilite have rounded shoulders.

Modeling in an A pose is so easy I have way more clothing modeled than I have time to  finish off.  That all said, I'm purely into dynamic clothes.  I most definitely do not know how this would affect conforming clothes.  I think dynamic clothes are key to supporting multiple figures and I definitely see more and more interest in them, but I'm very sure that conforming clothes are important to new figures, too. 

I really like the definition.  I already have several smooth, undefined male figures if that's what I'm looking for.  IMHO, the whole point of using a new figure is to do what I can't or find difficult with existing ones.  Realistic musculature is a big plus in my book, as is facial definition and sharp angles.
