The MCMG were in ROH back in February, facing the Kings of Wrestling, which ended with a DQ run-in.
It was later explained that TNA strongly requested their team not take the loss (and didn't make this clear until late on.) ROH didn't want their team to lose, so the DQ finish. ROH probably isn't up for doing it again, but who wins and loses doesn't matter as much on a random indy show.
There are still significant issues needed to be worked out. It is not a guarantee there will even be a deal, but most likely there will be as there have been negotiations on the different issues all week.
