This has popped up on a few sites recently as the description going along with the boxes for the upcoming Magic set:

[easybox]In their quest to uncover ancient treasures, Planeswalkers have awakened the Eldrazi - parasite titans of the aether, imprisoned on Zendikar for thousands of years. Seemingly unstoppable, these world eaters threaten all of the Multiverse and their very presence has changed everything you know about Zendikar. To survive, you'll have to be at the very top of your game. Rise of the Eldrazi is set 3 of of 3 in the Zendikar Block.[/easybox]
