Checking today I see it's not exactly going gang-busters for the two current projects.
Unicron = 31.8% backed (2546/8000) with 16 days left
Cookie Monster = 15.4% backed (462/3000) with 10 days left
For comparison, the Sail Barge was at 60% (3002/5000) with 13 days to go. The number of orders for Unicron isn't tracking that far off what the Sail Barge did, it's just Unicron's much higher 8000 threshold that makes the overall % look bad. Unicron succeeding is still possible if it gets the same kind of push as the Barge did in the final two weeks.
I wonder if Hasbro has plans for a 'kicker' for Unicron to get the buzz going again?** (Like adding Carded POTF Yakface did for the barge.) I saw they added a 'plush cookie' to the Cookie Monster HasbLab project but I don't think that'll move the needle enough for him to make it to 3000.
edit: **today they announced Unicron has a removable head with an alternate 'damaged' faceplate you can use to replicate the end of the 1986 movie.
