We're almost there. Just an epilogue and a prologue away from the completion of the Alicization arc. This arc is longer than all the rest of SAO combined, so it's a rather big deal to reach its ending. This was the final chapter of Alicization, but it still ends on a cliffhanger. We have to wait until the epilogue, I guess, to see if Kirito and Asuna can rejoin the real world.
There's no telling how long it will take until the anime reaches this point so it would be wiser to just hurry up and read it all. As usual the translation can be found over at defans translations.
