This is exactly what I've heard, too. The strength of the axle is more that adequate for 126 mm spacing, marginal at 130 mm. Shimano went to a three-bearing design (I think?) to support the axle. Campy followed suit as soon as they could.

Edit: Never mind, Post #15 has it right. It's improved bearing PLACEMENT, not the number of bearings.
