As expected in the glorious age of the internet, someone managed to record and upload the majority of the My Little Pony SDCC panel this year. It's grainy and from a side angle, but you can still get a good enough idea of what is happening throughout. They also included the clip we haven't seen yet to go along with yesterday's Equestria Girls one.
Head on down below for both parts!
Thanks to Miak for sending it.
