The Future:
Return to Theros (likely February for those asking): Hype level is high - here's hoping we get God-Gideon, the overthrow of Heliod, and the Return of Elspeth. Devotion has been forecast as coming back for a while now so that's for sure returning as are enchantments. I too am curious what an "Underworld Focus" means.
Ikoria (likely late April/Early May): Given that set symbol and "wild mechanic", I think this is for sure Kaiju world and also sort of imagine we'll be getting this as our new take on an Asian world - while it may have more of a Pacific Islander theme, here's hoping for some Samurai and Ninja to fight the Kaiju menace! Given that we're getting two very top-down sets in a row though, I imagine this set is a more "crunchy" bottom-up battlecruiser set. "Build you own monster" should play well with the usual Theros themes of dropping tons of buffs onto titanic threats.
Zendikar Rising (next September): Traps, Landfall, Quests, Allies - everything we loved the first time with none of the icky Eldrazi nonsense! Can't wait! Here's praying we get the fetches in Standard to end the scourge of their price, once and for all. I sorta doubt it...but a guy can dream.
The Cards: Tons of great stuff for Commander, as befits a Brawl dump.
Tome of Legends is a real card. The Commanders are just okay, but Tome, Arcane Signet, and new Command Tower art mean I'll be buying at least one and maybe two of the new decks.
