This site is noted as being a checklist for 2015 SDCC exclusives, but it doesn't include the My Little Pony exclusive, so it might be far from complete.

It is still a lot of exclusive items for just one convention, and many don't get released anywhere else later.


(one of the MLP exclusives this year is a pony in a chicken suit, packaged in a KFC-style bucket... dare I ask what the significance is of a pre-fried Pony in a Bucket?)
