New timetables - postponed!

Stagecoach had been planning to introduce new Busway timetables on 1 March (following on from last year's consultation, and the acquisition of additional vehicles). Although the intended timetables are now available to view on Traveline, the rather more important piece of news at this stage is their introduction has been postponed to "an as yet unspecified date". This date will presumably be the one when Highways England and Cambridgeshire County Council finally manage to reopen the stretch of Busway between Histon and Orchard Park. Anyone like to hazard a date for this (I feel I should offer a box of chocolates for the most accurate estimate...)?
