If the rumours of the set after Innistrad being Ravnica are true, then I'd expect a reprint of all the shocks and Dark Confidant (probably with his art butchered).

I'd also expect a real life "Master's Edition" of Modern Cards as a way to support the format. Duals, Fetches, Bob, goyf, cryptic, mutavault, etc. Maybe $10 for a pack of 3 Modern Staples?

Also, I don't see a problem with Goyf being back in standard. The removal is currently top knotch, mana fixing is pretty bad with the rotation of Zendikar, and if Innistrad is a graveyard set, I'd expect a shit-ton of graveyard removal to screw with Gofys.
