Currently listing on Newegg for $42/$64/$119 for the 120/240/480GB.
$119 for a good name-brand 480GB drive that performs decently enough is good to see, as a 1TB drive should come in right around the $200 mark.
The only thing is, and it's probably why the 960GB hasn't been released is that based on the performance of the 480GB drive they probably have to put in and validate a different controller. The 4 channel controller would just run out of bandwidth trying to handle all the data and would lose out on the parallelism which makes SSDs as fast as they are. So - they'd need an 8 channel controller for sure which might jump the cost a bit.
