At the moment, there's no way of telling if the H1 and H7 names will be used for commercial products. However, if that's going to happen, these will certainly be Android-based devices (since the Galaxy brand is exclusively reserved for Samsung's Android line-up). Of course, these could also be tablets, or different products.
As you may already know, since last year Samsung introduced no less than three new series of smartphones: Galaxy A (including premium, metal-made handsets like the Galaxy A7, Galaxy A5, and Galaxy A3), Galaxy E (including the Galaxy E5 and Galaxy E7), and Galaxy J (including the low-end Galaxy J1).
P.S.: The smartphone pictured above is the Samsung Galaxy A5.
