It's been two years since AWOK was originally released. I'd rather they get a NEW game underway. Also, the reason they released 2 of the 3 polled DLC items is because they took too long to get the poll online that they had already started work on what they thought would win, which was the Graveyard DLC. When Candyland won they had to quickly get that started and completed (and it shows).
As per a post NinjaBee made on their facebook page,
"Not sure if there'll be more DLC. It's still on the table. But then again... so is a whole new Keflings game altogether"
