By iota, I mean, an iota, like, 40 frames total. That's it. I don't know who spotted this, all I know is it showed up in the feed at Rainbowdash.net (which is sort of like a twitter, but for ponyholics). From what I can gather, it aired today, and a trip to Equestria Daily seems to indicate that it is indeed a new commercial. The original can be found here, and can be seen on YouTube below!
This doesn't confirm anything about season two, other than that it exists, and that is awesome.
