I don't know if there's any substance behind it, but there's been rumblings for a while that people were growing frustrated with Delirious's direction for the company. It's been cited as the reason guys aren't re-signing and why Corino left. Plus ROH sent a letter to WWE over Corino visiting the PC while still technically under contract so now WWE won't talk to guys until 60 days after their ROH deals end, which surely has pissed some guys off looking to take the next step.
