The WS-Desc team determined that the spec it was developing was 
sufficiently different from WSDL 1.1 that it was more appropriate to name 
it WSDL 2.0 rather than WSDL 1.2. So the team simply changed the name from 
WSDL 1.2 to WSDL 2.0. You should think of the last WSDL 1.2 working draft 
as an early version of the current WSDL 2.0 working draft.

SOAP 1.2 is complete, and developers can use WSDL 1.1 to describe SOAP 1.2 
services. But the fact of the matter is, very few products fully support 
SOAP 1.2, and anyone developing Web services using SOAP 1.2 will probably 
encounter interoperability issues for the immediate future. I agree with 
your third assumption.
