I'm really impatient and would like new demons to play with. It probably wouldn't help releasing another expansion so soon with all these balance issues, but hey, I don't really give a f*ck. Balance issues will always be around I figure.
The midterm exos satisfied my wanting for new runes for the time being, I'd rather wait until we get a little bit more balance before adding more new runes into the mix.
As much as id like new stuff. I think they would come out and get easily overlooked among all the issues we have going on or would further underwhelm the people who yearned for them since we've yet to solidify identity, design, or power.
All I know is if they release an expansion, I won't buy it. I support DOG, in general, but choosing to release more content before the existing content and promises are sorted out is currently out of the question (for me).
