You say it like every single sale of the game outside those reported is on the PC. While the actual numbers here might not be accurate, the trend is clear for all to see. Any sales that this (rather large) sample has missed out will probably follow the same ratios of console sales outnumbering the pc by 10:1 or some such ridiculous number. And either way... 10%, 15% or whatever... it is dwarfed by the console numbers.

The 'PC gaming is dead' myth needs to go away. Having said that, it still is quite insignificant compared to the consoles. It's still viable, obviously, but it is losing importance.
