The new channel will feature five days a week of geek-themed programming from Day and fellow famous geeks Wil Wheaton, Paul and Storm and Veronica Belmont, plus a series of motion comics from publisher Dark Horse.
Day will host a video blog called The Flog, while Wheaton plays tabletop games and RPGs on TableTop (looks like Freddie Wong makes a guest appearance, too) and Belmont hosts a sci-fi and fantasy book club called Sword and Laser.
Paul and Storm's scripted musical comedy, Learning Town -- co-starring Dr. Horrible co-creator Maurissa Tancharoen -- will kick off in late 2012.
Other shows include "Written By a Kid," where directors turn kids' wild ideas into short films, and of course, the latest episodes of Day's The Guild.
Geek & Sundry launches April 2nd, although some of its shows won't arrive until later in the year.
