It sounds like larger wikis have priority (I am almost 8k articles on my wiki and I am still on Legacy but another wiki I use to edit on is UCP but they had 14k+ articles), I think wikis with less than 200 pages like yours will be close to last. UCP migration seems to be aimed to wrap up around December.
