Why new Python 2.5 feature "class C()" return old-style class ?

bruno at modulix>Since the class statement without superclass actually
creates an old-style class, I'd expect the "class MyClass():" variant
to behave the same.<

In Python 3.0 I really hope the

class C: pass
class C(): pass
class C(object): pass

will mean the same thing. (So in Python 2.5 the second version can be
made to mean the same thing of the third).
