Rumor shut down.
Then again, not even Zampella knew last time, lol.
That's because the publishing rights for the first game were sold to EA.. Respawn gave up their right to have any control over where the game was published in that deal.
They've made it abundantly clear that they retain the rights to decide on future games.. and are now making it clear that they definitely didn't sell those rights to MS.
They didn't sell EA the franchise so they'd know.
