Not to get too much off-topic here but I thought the general rule was they would announce next year's movies closer to the release of the 3rd movie in a certain year (so with The Long Halloween Part 1).
As for Hourman, this does seem like it's going to be his biggest animated role so far. Previously he only briefly appeared on JLU and Batman: The Brave & The Bold, plus some cameos in Justice League: The New Frontier. I don't think there's really that much to talk about him so far, not enough for a retrospective anyway.
EDIT:
Another interview with Jeff Wamester.
