I can't say I can tell any speed difference between the new and old 404's. Of course, any difference would be small enough as to not be perceptable.
As for handling in cross winds, the new design might be a little less prone to getting moved around. However, I haven't ridden them enough in stiff winds to convince myself that's true, or to rule out the placebo effect.
The old 404's weren't all that bad in crosswinds. I used to have a set of Ksyrium ES's that were worse. The new 404's feel a little better to me in a crosswind than the old. Maybe I'm more sensitive to that because I weigh 135#.
