Just yesterday, Wizards and Hasbro Toys revealed a preview of their exclusive product for the upcoming SDCC 2017 and they called it Magic: The Gathering 2017 Planeswalker Pack. The product is priced at 180 usd and the features are the following:

• Includes a 24” x 36” screen print of Nicol Bolas illustrated by Brandon Holt. Produced in collaboration with Mondo. Printed by D&L on Magic: The Gathering card stock. Nicol Bolas is an iconic Magic character who first made an appearance in the game in 1994 and has been a powerful fan favorite since.
• 6 Planeswalker cards with exclusive artwork by illustrator, Vincent Proce
• Characters include Gideon Jura, Jace Beleren®, Liliana Vess®, Chandra Nalaar®, Nissa Revane & Nicol Bolas

The planeswalkers are on their recent card printing according to a post in Reddit:

Jace, Unraveler of Secrets
Liliana, Death’s Majesty
Nissa, Steward of Elements
Chandra, Torch of Defiance
Gideon of the Trials
Nicol Bolas, God-Pharaoh

Update: Here is a close-up scan of the six planeswalkers

I would have it as an exclusive collection to display in a living or in a local game store or whichever you prefer. It would be remained unopened to preserve the mint value of the product if ever you’d plan to sell it later on.
