The kind folks over at Equestria Daily have recently posted some pics from upcoming additions to Hasbro's MLP toyline (see photo above) as well provided a video of a new song from Season 3 of the series and a few highlights from a Q & A session with some of the staff (read that here)!
Ah Comic Con! Tis the season for spoilers galore!
UPDATE: A higher quality version of the Twilight Sparkle/Spike duet from the first link has recently been posted on EQD alone with another brand new pony tune. Check it out!
