Well, this one kind of came out of left field.
Yet Another Pony Podcast did a special toy episode where they cover a wide array of pony toys. The Canterlot playsets and the papercraft sets were some of the ones they covered, and you can find that podcast here.
But also included with the email was an interesting addition- an interview a friend of the team did, by the name of Midnight Dreams, with Ellen McLain, the voice of GLaDOS in Valve Software's Portal and Portal 2. They asked her some questions about ponies, and she said she'd gladly (ha) voice a pony if Studio B asked her to.
You can find the video after the break.
