My conclusions after reading the digital euro prototype summary report and the longer political report.

They are determined to launch a successful product. They have been working with experienced and smart engineers from large fintech companies. They will move forward with this and probably make the product attractive enough that it can be widely adopted. They will include many attractive features copied from Bitcoin to attempt to convince the public that it has privacy and user control.
At the same time it is fully centralised and includes enough back doors that they can change the terms once target adoption is reached. Programmability and conditional payments will be in it, but probably restricted until they are ready to spring them on an unsuspecting public. Surveillance will be initially covert, but the tools are there to do mass surveillance via big data. Big regulatory exceptions will be carved out to weaken privacy and allow it "for the right reasons".
Banks and payment providers will get a piece of the cake to get them on board. They will drive most of the user onboarding.
