The roadmap doesn't specify a time frame for each phase. The start of a new phase could happen tomorrow (no, definitely not) or sometime later (until users completely forget about it).
There are no exact dates, but the way it was written suggests that we should already be somewhere between phase #2 and #3 if everything went according to plan. A few days after the roadmap announcement, they were supposed to release a Ledger Recover whitepaper and technical posts explaining the Recover feature. And a few weeks after that, parts of their Recover framework was supposed to become open-source. Etc., etc.,. It's just a waiting game now.
