No one has responded to you because this is kind of a boring answer. But I can tell you right now he's probably the most spot on person in this thread. Everything he's said seems the most reasonable. They're not doing new races because the remodels are supposed to fill that void. Furthermore, we don't need a new class because they just released one.
I know you're not exactly going out on a limb here, but come tomorrow - this will be the most accurate response thus far.
