nah, we'll still have the environments from FO 1&2, and it'd be much more appealing to see differently built people anyways, I'm all for the 3d models being implemented, but I'm too busy to try my hand at anything to do with 3d modelling at the moment.
and there's also the different armour that has to be made through the 3d,because as we all know only the bluesuit, PA & LJ was made, and the models in themselves have incomplete animations, so there's still about 75% work to be done after the weapons are completed really...
