"Talk about an odd day. We don't normally comment on rumors, but this one seems legitimate enough to write on. A user on NeoGAF has spotted an odd discrepancy where Metal Gear Solid V receives the subtitle The Phantom Pain. And this is somewhat surprising, considering that we've believed the Phantom Pain to be a different game than MGSV. Could they be the same?"
I don't think the article mentions a new IP anywhere, so, if that was confusing, I apologize!
Thanks for the note.

It only really confused me because the picture of the cropped in Metal Gear Solid V into the screen cap of The Phantom Pain has been around since the VGAs.
