Could we see other class systems like Prismatic?

Could we see another “side-class” like Prismatic?

Whatever Bungie does with the third darkness subclass - the prismatic class has potentially opened up room for our characters to gain other sets of powers outside the traditional Light & Dark subclasses.

They could give players the power of Taking. Or simply calling it “Blight”

They could go back to the Dragon / Ahamkara class theme concept art and do something with that

Or nano-machines

But what do you guys think?
