I picked one up today at target. They had to pull it from the back, not on display yet.
The case has a slight bit of a hump to it to accommodate the pop socket. The socket is a new design, not compatible with the old ones, so I don't think you can put your old caps on the the new socket thing. The pop part removes with a twist, leaving a little base behind.
They left the hump part of the case hollow, so the whole thing is VERY light. Might be space behind the hump for a folded bill or two of cash.
When folded the pop socket is a lot less annoying than one stuck on a case, but it's not as flush as I would have expected either. It's clearly a compromise between bulk/wasted space, and keeping the socket from snagging on things.
