Fringe: The Complete First Season is now available for pre-order on Amazon in both Blu-ray and DVD formats for $55.99 and $41.99 respectively. The release date has not been announced yet, but it is estimated to be sometime in August.
BTW, one of the nice things about pre-ordering on Amazon is that you are guaranteed the lowest price, even if the price drops between now and the release date. Plus, either edition should qualify for free shipping, and you don't get charged until it ships.
However, if past performance is any indication of future outcomes, I would expect to see several "special-editions", as was the case with Cloverfield, Transformers, and the first few seasons of Lost. Of course if that happens, we'll let you know about it.
