Or at least, it's as officially "announced" as an indie game can get. Brilliant madman Edmund McMillen's been gradually revealing gore-spattered bits and pieces via Twitter , allowing a few particularly interesting tidbits to slip out. Foremost, the expansion will increase the total item count to 205 (up from 131) - thanks in part to a new "trinket" item category that grants passive bonuses. Also, it'll go for a mere $3 when it's ready for primetime. Sadly, there's no release date beyond "when it's done" at the moment, but there are worse fates. For instance, being chased into a monster-packed death dungeon by your crazed mother. So that's... comforting? Well, I tried, anyway.
