Ok i could not find a straight answer, so well got to ask.

So cs50x is recorded lectures from Harvard's cs50 fall class, as far as I understand.

So as of right now the cs50x lectures would be fall 2014.

Will cs50x update on a weekly-ish basis when we hit fall 2015 so cs50x lectures are from 2015, or will it run as fall 2014 until the end of 2015?

I would love to know this, as i am gonna start the course on edx, and if they will update the videos during fall i rather wait, but if it wont be updated untill 2016, i want to start straight away.

The 2015 edX course uses the 2014 Fall Harvard lectures. They will not be updated, as the course runs until 31 December 2015.

The 2016 edX course will then use the 2015 Fall Harvard lectures.

So you can start now.
