Perhaps the most significant announcement was for two upcoming sets that will be making a splash in the game. Kaladesh is the first of two sets in the Kaladesh block. It will have 264 cards, and have prerelease events on September 24 and 25, with an official release set for September 30.
The follow-up, Aether Revolt, has 184 cards, and has prerelease events on January 14 and 15, 2017, with the official release the following weekend on January 20.
This block focuses on the plane of Kaladesh, where popular planeswalker Chandra was born. Expect a middle-eastern feel along with some degree of steampunk influences. MSRP for both will be $3.99 a pack.
Viz Media announced a third volume of its Art of Magic: The Gathering series, this one focusing on Kaladesh (see "Art of 'Magic: The Gathering -- Kaladesh'").
The Magic "Fat Pack" is being given a facelift and a new name. Now called a "Bundle," they will be introduced with Kaladesh and include a decorative, reusable box with key art from the set, an 80-card land pack, ten booster packs, one player's guide, a spindown life counter, and a rules reference card. MSRP will be $42.99 and the first Kaladesh Bundle will release this fall.
Several new Magic: the Gathering Commander Decks are scheduled for release as well, each featuring 100 cards and a four-color Commander. Five such decks release on November 11, and together there will be 56 never-before-seen cards legal in Vintage and Legacy. MSRP is $34.99 per deck.
Planechase Anthology showcases cards from Planechase and Planechase (2012 Edition), collected together in one package. It features four preconstructed 60-card decks, with a total of 32 rare cards, 86 oversized Planar cards, four slide deck boxes, an oversize slide deck box, 45 double-sided token cards, a special edition planar die, four spindown life counters, and a strategy insert. MSRP is $149.99 and it releases November 25.
Magic: the Gathering: Conspiracy: Take The Crown was announced earlier this year with an August 26 release (see "'Magic' Set Gets Name Change, New Images"). MSRP will be $11.99.
Moving forward, Wizards of the Coast has announced that there will be two major product announcements every year – one in the fall and one in the spring. The next announcement day is scheduled for September.
