Yup, you read that right – at least 5. In 2010, it was just the Samsung Galaxy S, and then followed by the Samsung Galaxy S2 which was accompanied by the Samsung Galaxy Note in 2011, bringing the total number of flagship models to 2. Subsequently, it was remained that way until 2014, where there were three flagship models during that year. 2015 then saw a quartet of flagship devices being announced, and this would include the Plus and Edge versions of the Samsung Galaxy S6, and hence he claims that there will be a minimum of five flagship models next year from Samsung.
On what does Evan base his assumption on? We do not really know, so do take this with more than a pinch of salt.
