For those who are curious, VGChartz is now projecting 1.68 million first-week sales (week ending December 24th). I should note that VGC's first-week estimates are often conservative and are adjusted as more data comes in.

It was the top-selling game (on any platform, including consoles) that week.

Edit: I don't understand where the WoW discussion is coming from. I obviously didn't post SWTOR sales data in the SWTOR discussion forum to take a stab at WoW players or suggest that it's going to "kill" it or anything else.
On topic: I realize that VGChartz isn't especially accurate, but it's the first data/estimate out thus far and figured other people may find it interesting as well. Even if the numbers are off by +/- 100,000, they're crazy high.
