Sega is apparently the high bidder for developer Relic Entertainment and its games in the THQ asset auction.
The high bidder for Saints Row developer Volition is apparently Koch Media, parent company of Deep Silver (Dead Island). And the high bidder for Obsidian's South Park RPG is said to be David Dickinson, er, I mean Ubisoft.
This is not official yet. The auction is off-limits to most people. The scraps of evidence come from those apparently close enough to know what's going on.
