Honestly, it currently goes like this for A-1 Pictures:

7 July, 2012 - 22 December, 2012: Sword Art Online

31 December, 2013: Extra Edition

5 July, 2014 - 20 December, 2014: Sword Art Online II

This means that since Kawahara-sensei (I refer to him as such since I have a lot to learn from him) has yet completed the novel version of the Alicization arc, and is also writing a new series for the franchise while reworking on two others, the following schedule for A-1 Pictures should be assumed as such:

31 December, 2015: Extra Edition II

9 July, 2016 - 17 December, 2016: Sword Art Online III

31 December, 2017: Extra Edition III

Because remember, folks... This requires a lot of work and money. And seeing how Kawahara-sensei (see explanation above) wants an Accel World II to be made, it is up to those tied to this project to decide if they can make this series and have it start at the start of the summer season.
