I don't think there will be a new SE2 this year; but they may update the storage to 32GB and 128GB similar to what they did with the old iPhones and iPads when the 7 came out.
Aside from the usual people like Ming-Chi Kuo saying no new SE2 is coming out we don't have any leaks of a new SE by today.
Looking at what happened last year, we had rumours of a 4" iPhone coming out for weeks, then leaks of the name "SE" and actual pictures in the fortnight before 10 March when Apple announced a special event on 21 March.
Looking at 2017, we only have rumours of a 128GB version and suggestions of s 32GB version.
