I haven't actually played Dead Island or Risen yet so I don't have an opinion on them owning Saints Row & Metro. Hopefully they treat them well and I agree that those are (in my opinion) the banner IPs I cared most about.
Edit: No mention of Vigil, developers of the Darksiders franchise. Wiki says:
Although much of THQ's assets were sold in an auction as part of bankruptcy hearings, THQ is still seeking a potential buyer for Vigil through reality TV shows.
...but doesn't actually have a linked citation to look at.
