Today Aaron Forsythe was on the ProTour webcast and announced "Modern Masters," scheduled to be released in June 2013. Apparently, it's a limited-run, draftable reprint set that features exclusively Modern-playables.

229 card set, 53 rares, 15 mythics. Comes in 24-pack booster boxes, MSRP $6.99/pack. Each pack comes with a foil, no basic lands. Goyf is confirmed at Mythic.

With all of the recent discussion about Wizard's support of Legacy v. Modern, I find this pretty interesting.
