Actually I'm not sure if it's new! I filed it away in the nightly roundup folder earlier today so I could dig around past news stuff for it.
Anyway, this DVD apparently holds Swarm of the Century, Sonic Rainboom, and The Cutie Mark Chronicles.
I'm not sure if Hasbro plans to release all their DVD's in this format, but so far we have the "Ticket Master" solo, the Canterlot set, and now this.
Here's to hoping they drop a box set with special features some time in the future. I think the best thing we can do as a fandom is continue to grow, so stuff like that becomes more financially sound.
Thanks to DANTE for the images/heads up!
