I believe phil Spencer about xbox one sales, not these so called insiders. Also vgchartz sales has never been right concerning xbox numbers , even during xbox 360 days. They were always off every time, I believe xbox one numbers are at 38 million or above that figure. Anyways I'll always trust phil over some biased so called insider.
Problem is XBox always was overtracked, not undertracked on VGC.
I just wonder why anyone would trust Phil, after all the lies of the last 4 years.
