There's some confusing information circulating around about the campaign regarding the total number of backers across multiple regions. Someone emailed Hasbro's Customer Service asking about the number of international backers, and how those totals would impact the campaign. Hasbro's response was that the Asian market backers would be added to the number for the US, UK & EU at the end of the campaign.
If you browse to the Hasbro Pulse stores in Asia (I went to the Hong Kong page) the number of backers right now is listed as 9,364. But if you check the US, UK & EU version of the store the number of backers is listed as 9,523. The numbers are oddly close to one another - less than 200 apart. But if those numbers are to be believed, they come to a combined total of close to 19,000 backers! That would unlock all of the tiers. The guys at the TVC Facebook group commented on this, and they're evidently reaching out to Hasbro's PR group for clarification on this.
