The interesting part about this class is that it is a lab class, yet it is trying to be accessible to anyone and everyone around the world. It will be interesting to see the logistics of how the MITx people handle grading, forums, homework, questions, and all the hard systems problems when 6.002x finally gets underway.
The other question is how will this compare to 6.002 as it is currently taught at MIT - will 6.002x be at the same standard? You as a student in 6.002x won't have the same chance to interact with your classmates as in a traditional MIT course, so can it be considered the same type of class? This all remains to be seen.
