Gaming analyst ZhugeEX or Daniel Ahmed has released information regarding the very secretive total for the Xbox One. He said they are up YOY in the US but never mentioned it being up YOY WW. He also mentioned digital sales are high but that the total install base is only around 41m. That's about 2m lower then we have it here on Vgchartz so we might want to make some adjustments.
