We don’t know yet if the routes announced on May 4th are new routes or existing ones that will be bundled with the paid Rush Hour update. Generally new routes are added when they have been given the green light and are in the planning stage.
when they're actually in development when they're ready to announce them In the case of rush hour (the 2022 route bundle) they're going to announce which routes will be included on May 4th, and the roadmap is updated that day also, so I would expect some new routes to be on the map next week
