I just heard from an SA that the medium size is coming out the first week of June (3rd I think) along with its own selection of colors for that size. I was in the store comparing the small (which I found to be almost like a fanny pack/belt bag on me) and the large (similar to the size of a CF Jumbo but with a much shorter strap) and wishing there was a medium option and the SA confirmed and said she would give me a ring once the mediums are available. 
I can't wait to see the color combos because I would love to see more options with the silver hardware.
