Pretty sure it wasn't a question, as much as "I am 100% certain that Gears of War 2 only sold 2,1 million during Friday-Sunday because these guys say it topped 2 million in that time".
Either way, you gave an explanation about Gears 2-sales, so I don't see how it matters anymore.
EDIT: ACtually, that's more what it deteriorated into. From the beginning, the question was just if the sales on VGChartz for Gears 2 were from Friday+Saturday or all the way through Friday-Sunday.
