if the charts of dec 21 puts it at 1.3m, then RIGHT NOW, january 4th, it's really close to 2m. if the charts are adjusted, it will be up.
Based on what? Your hopes? Because nothing suggests it will be up. It did 215k in November NPD and you're expecting 600k+ for December. That isn't logical based on November sales. So yeah, it'll be adjusted down in January when we get full figures. Brace yourself.
