I'm surprised at the 100 student limit they impose. I'm currently following MIT's 8.01x Physics course on edX along with 33k other students. So far I haven't had an issue that's a direct result of the number (like felling I don't get enough attention from the staff.)

So on one hand we have options like edX, which reach a lot more people and are mostly free ($50 for a verified diploma) that reach orders of magnitude more students, and on the other a paid-and-accredited degree.

I personally hope they'll be more of the first ones, because of a) not being able to spend $6k and b) the warm feeling I get in my stomach when I think about free and high-quality education that reaches tens of thousands of people.
