Time periods are very rough due to different areas in the country being ahead or behind then others in the rollout.
Each phase i would guess is quaterly so 3 months between them so something like this below:
Phase 6 Jan to March
Phase 7 April to June
Phase 8 July to September
Phase 9 October to December
Though when the next exchange list is announced and spreadsheet leaked we shall if there are more phases this year, though with these rough dates delays will push cabinets and exchanges beyond the phases they where planned to be enabled by.
