Ring of Honor released the following statement moments ago through ROHWrestling.com and their social media accounts:

We have just received word that Samoa Joe will be LIVE in Las Vegas at the Orleans Hotel & Casino this Sunday night.
He has something to say, and wants the world to hear it.
This will be Joe’s first appearance in ROH in over seven years, his first ever non-TNA pay-per-view appearance and his first post-TNA appearance since parting ways last week.
