How much cut and how much paste for the 'new' deal?

Are we or are we not edging towards a Brexit deal? My round-up of today’s news leaves me none the wiser. Given that all the attention has been focused on a replacement for Theresa May’s Withdrawal Agreement section on the Northern Ireland backstop, one wonders if anything else is being considered—things which hardened Brexiteers got quite wound up about, such as a divorce bill of £39 billion for example. That figure is not mentioned in May’s Withdrawal Agreement, but the methodology for arriving at whatever figure it might be is there in Article 133. Will Johnson want that changed? Surely he’s led us to believe that we’d only be paying the E.U. a few peanuts to leave? Then there is the question of the Transition period, which I assume would still be two years. During this period the U.K. has to accept whatever rules and regulations the E.U. decides (and contribute financially to E.U. programmes), but will have no representation. Presumably the current negotiations will be taking that on board too, to reflect the U.K. government’s ‘hostile environment’ for all things E.U? We’ll soon find out just how much of May’s 139-page Withdrawal Agreement will be left untouched. I suspect most of it.
