Well the idea of an evolutionary plateau is supposed to describe an extended period of time where there is relative stability in the shape of something - an ideal form for the given environment.

With computer hardware evolving by a magnitude every 18months or so there's always going to be some cool new thing we can shove into software. With 3D figures it can obviously continue evolving until they are perfect replicas of human beings right down to the molecules.

However, I'd be quite happy with a "rest" period somewhere in the middle of the super-evolutionary pushes where Poser figures look and bend like real people on the outside and can wear realistically draping cloth along with belts and armor and other cool hard-edged stuff etc.

At that point it would be a "finished" product in my opinion as it would have finally delivered on the promise of Poser itself - the digital mannequin/figure for artistic reference etc.

After that it would be "Poser Plus" or something.

But actually, I think if Poser reaches that ideal "plateau" it will be in competition with Max, Maya and all the high-end apps response to the virus that is Poser in the 3D world, heheh.
