THQ is hurting right now. They're being hit with layoffs and the CEO took a 50% paycut. It's not looking good, but perhaps there is an opportunity here. Games like Red Faction, perhaps Warhammer 40K and maybe even "newer" games like Company of Heroes and Destroy all Humans could find a home here.
I also don't know if Relic still holds the rights to Homeworld, maybe that series could come over as well, since it doesn't appear to have been given to GOG through Activision.
If worst comes to worst, someone will buy them out. There are enough seriously wealthy young tech entrepreneurs out there who would take it for sentimental value/bragging rights, with the intention of turning it around.
We'll know for sure around July 23rd, but the chances of them regaining their public listing before then are minimal to none.
