As a general prediction, I am not sure that I can see much difference between these:
In the future, people will wear bacofoil suits.
In the future, people will be wearing bacofoil suits.
However, if we put a time reference in, things changes:
By 2020, people will live on the moon.
By 2020, people will be living on the moon.
In this case, the second sounds much more natural to me.
