Prolific leakster, @evleaks, has posted a Tweet that simply says, "Well isn't this interesting..." and shows an image of what appears to be a stock control system showing that there will be four variants of the Samsung Galaxy S7, which is due sometime at the end of the first quarter or start of the second in 2016. The models highlighted are the Galaxy S7, Galaxy S7 Edge, Galaxy S7 Edge Plus and Galaxy S7 Plus. We are unable to verify this information and as far as we can tell, it simply consists of somebody having typed the model numbers onto a word processor - but it would follow something of the Samsung Galaxy S6 trend, although there is no Galaxy S7 Active listed. This is perhaps understandable as the Galaxy S6 Active is currently an exclusive for AT&T in North America.
The rumor may go against the other rumor we've seen detailing two model designation for the up-and-coming Samsung flagship model, which are SM-G930 and SM-G935 for the Galaxy S7 and Galaxy S7 Edge respectively. We have also seen that Samsung are to release the Galaxy S7 with two System-on-Chips, one variant based around the Qualcomm Snapdragon 820 and the second around the Samsung Exynos 8890. None of these rumors may be substantiated, but if Samsung were to release four models at launch it's possible that @evleaks has a red herring and instead, we'll be seeing two versions each of the Galaxy S7 and Galaxy S7 Edge, one using the Qualcomm chipset and the other using the Samsung processor. Should Samsung later release the S7 Active, this will likely use one or the other chipset assuming it's an AT&T exclusive, but then if later on Samsung release the S7 Edge Plus and S7 Plus, this could bring the total number of models up to nine. Let us not even contemplate the color variants we may seen from Samsung.
Unfortunately, in the absence of any concrete evidence, the above is conjecture and speculation. Over the next few months we can expect the Samsung Galaxy S7 family rumors to continue, and perhaps we will see some evidence to substantiate @evleaks' screen capture in the coming weeks and months.
