I am curious to start the course in 2015, and I was curious - as perhaps others are - whether the lectures will still be the same, or whether there will be new videos.
The 2015 Edx offerings of the course started on January 1, 2015. The Harvard University offerings, including the CS50 Certificate and Course Credit options, start on 26 January, 2015. The option comparison chart lists all this information, and more, including end dates.
The lecture videos will be different. This is stated on the page listing the differences between the 2014 and 2015 versions of the course.
New and improved lectures! Hopefully.
- Now available in 4K (via a link below each embedded video).
- Shot in anamorphic 2.39:1 widescreen.
- More on-stage demos!
I can also confirm this first-hand now that I've watched the first lecture from the 2015 offering of the course. It's different from the first lecture of 2014.
Check out What's new? for all the details on what's different for 2015.
- New and improved lectures! Hopefully.
- New CS50 Appliance, based on Ubuntu!
- Updated problem sets!
