Everyone has completely forgot about all previous announcements, timelines, and plans that the agency told us about forever ago, eh?
The "return" to manned missions through official NASA platforms was in the books before the Shuttle program was even given the order to finally shut down. They extended the Shuttle program longer than designed, iirc, and they had a plan to develop new rockets that would enable us to return to the Moon and, in time, to Mars.
The original time tables seem to be holding well, thus far. I think they originally intended manned flight in 2018, moon sometime between 2020-2025, with sights on Mars.
Then again, it seems the new time table is suggesting NASA isn't ready to put men on the new rockets they are developing. The original 2018 or thereabouts plan involved all-NASA product (which still involves Boeing and/or Northrop Grumman contracts, traditionally, for production of said rockets and vehicles... iirc), not contracting it out to private industry. The private industry contracts had originally been made to provide continued flight between the end of the Shuttle program and the start of the replacement program.
Then again, considering I can't be bothered to look up the facts and am only vaguely remembering what I saw years ago, I might have some of this wrong.

Come to think of it, I think 2018 was perhaps the first test of the vehicles meant to be manned in the first place, with actual manned flights occurring around 2020, with the Moon as the first destination following that.
