I think Liefeld is correct in that DC is in a management clusterfuck right now. I really doubt DC is going under. Even if they started doing losing money, the IP and merchandising that DC brings is too valuable to squander. Far more likely that WB would do a thorough restructuring and bring in a few of their own suits to run the place and make it profitable.
And while such things often go wrong, it's not like the current in-house management at DC has managed any better. Best case scenario, we get a (relatively) young hungry up-and-coming executive with an interest in pop culture.
The main risk long-term is that DC will end on a revolving door of WB managers, rather than a long-term publisher who understands publishing. But then I don't believe the current leadership at DC really thinks like publishers anyway.
