I asked casemate about it too and got this as a response:
"
Hello,
Thank you for contacting case-mate. Unfortunately, we were given a prototype Nexus phone device from Samsung that we modeled our cases from. When Samsung released the Nexus phone device to the public, they made minor changes that we were not aware of. These changes, affected the fit and function of the case. We have redesigned the case and the new cases will be available on our website in the next few weeks.
"
They're still saying "in the next few weeks" whatever that means. I think i'll wait for it. I've got my eye on that white and gray one
