This is just only going to create more bullshit for two reasons:
1) Instead of the figures, you'll have dingbats and nimrods discuss what Move sales are when Sony declares that it had a "15% increase in sales in Move over the past month." Of course, fantards will use the most optimistic number possible and treat it as standard. So expect about 30-40 million Moves to be sold in the US alone by the end of next year. It is the Walscuse of the old GAF days.
2) The usual sales bullshit will never go away but every fantard is going to shriek at the other side's projected (read: bullshit) numbers. This will mean anecdotal evidence will become standard:
"Kinect sold 150,000 last month? Shiiiiiiiiit son. Move sold like 500,000. There's this chick with big tits that was buying the Move and that is how I know it sold well - it is in the mainstream. By the way, that chick had a busted face so I didn't spit game at her. I only fuck dimes y0."
