No. Cubic Bezier splines are a special case of Bezier splines, which are a
special case of B-Splines, which are a special case of NURBS. With NURBS,
you can have

* arbitrary degrees
* arbitrary number of CVs, starting at degree+1
* concept of knots spans ("b-spline" part)
* arbitrary knot spacing ("non-uniform" part)
* arbitrary weights for each CV ("rational" part)

Surfaces are outer/tensor products of curves.
