Interplay: Fallout 6 could be ours. Bethesda: We own the Fallout MMO
Both Interplay's Eric Caen and Bethesda's Pete Hines have commented on the ongoing lawsuit between the two companies.

Caen states in his conversation with Eurogamer:
"But in that case, the IP will come back to us, and of course, we will complete our work and release Fallout MMO."
Caen's Fallout 5 refers to the next Fallout game from Bethesda, with last year's Fallout: New Vegas considered the fourth game in the hugely successful series.
"The original licensing deal was for three games and their DLC," Caen continued. "So they already did Fallout 3, then Fallout: New Vegas, and they can only do one more Fallout, 5, if the sale of the IP is cancelled by the court.
"We will love if we have to do Fallout 6 and sequels. But we will see what happens in court. It can be this year or later... We have the back-up of our shareholders to fund this fight."He continues:
Meanwhile, VG247 talks to Hines:
He continued: “We own the rights to everything Fallout. The licence is ours. Fallout belongs to us. That’s what I’ll clarify.
“Beyond that, I’m not commenting on anybody else’s comments. It’s a legal matter. A specific MMO or project or any of that stuff, the lawyers are all going to sort it out.”
