It looks like the Samsung Galaxy S7 will come in two versions (although the rumors are of course unconfirmed), and one of them will include a new Qualcomm processor, the Snapdragon 820.
And now a report in Chine says Snapdragon 820 will be exclusive to Samsung until April 2016. This means no other phone manufacturer besides Samsung is making any phone containing Qualcomm latest chipset. In that scenario Samsung might be ahead of its opponents.
The same report says the S7 will be unveiled in February and starts shipping in March.
