I'm waiting mainly for Android games or Android versions of existing games at this point:
Broken Age
Broken Sword: The Serpent's Curse
Paper Sorcerer
Deus Ex: The Fall
Rival Threads : Last Class Heroes
A version of Shadowrun Returns with real saves
A Detective Grimoire version with fewer bugs
On the PC side I'm waiting for:
Tesla Effect
Gabriel Knight 1 remake
Wasteland 2
Various other Kickstarter projects (Shadowrun Online, Spate, Shadowgate, Mage's Initiation, ...)
