More to the point, I was looking at the same course the other day and it doesn't appear to be open yet for general enrollment -- when it begins its first year in the fall, enrolment will only be an option for certain corporate partners of Georgia Tech, and their sponsor in this endeavor, AT&T. In other words, either you or possibly your parents probably have to be employed by AT&T or one of those corporate partners. Enrollment is also limited this first year, so even though its an online class (MOOC), its not like just anybody with seven grand is guaranteed a seat. They intend to widen registration over the next 3 years.
I could have interpreted wrong, but that's my understanding of the situation. It's still very interesting, and a good deal if you want a diploma to go along with your learning. I'm planning to keep an eye on it myself. But if you just want to learn, which is nearly every bit as good, I believe Stanford and/or MIT make all their coursework and lectures freely available to learn from.
