In a most intriguing turn of events, a  YouTube video surfaced that appears to be a leaked 'trailer' for Magic 2013/Duels of the Planeswalkers 2013. Similar in form to the Gideon trailer for Magic 2012, the video depicts an introduction for each Planeswalker, each animated in the "motion comics" style. The Planeswalkers present in the video are Chandra, Jace, Garruk, Liliana, Ajani, and Nicol Bolas.

The user behind the video has also uploaded it in multiple languages.

Does this mean that the 'Lorwyn five' are back in Magic 2013?

Could it mean that Nicol Bolas is in Magic 2013, along with the first appearance of gold spells in a core set?

Only time will tell.
