I saw a quote from someone just now:

Video from PAX East 2015 speaking to tank role design decision.

This doesn't mean they will be releasing Samurai in the future and this also doesn't mean if they do release Samurai it'll be a tank role, but it was considered to be a tank role at one point in time when deciding the jobs for Heavensward.
yes please o.o/
