Here is the lineup 
And they have released the Pricing for them.
My own thoughts: Looking at the price they are not for casual users, but having the amount of cores and being able to overclock will be of interest for those who can make full use of it such as content creators, knowing first hand how long it can take to render videos especially in high definition having the extra grunt would save time. I think a lot will depend on how well it does when put to the test compared to the other processors that Intel offers, and then we will see if it is worth the cost.
