So far, it's on Amazon for sure. Not really a picture displaying what it'll look like, but it is $180, and includes (of course) ALL episodes with more than likely to-be, at least to some extent, limited and special packaging. It does not say if it will be here by the end of the year like Dexter's complete series or not, but it should be updated soon. If you already own seasons 1 - 5a and just want 5b, then that is also available for pre-order. As goes for the standard release of 5b, there is not any picture displaying if there will be exclusive stuff in it. I do not know if what you see is the final cover photo or not yet, but will try to keep an eye out and keep updating. Also a strange thing is that unless I missed it, I cannot find the complete series on DVD. Here are links -
