You realize that many systems outsell their launch weeks later in their lives. The DS has had weeks that sell more than 2 million systems. I'm sure the PS2 has as well. The Wii sold just over 500,000 consoles worldwide on the week of its launch according to vgchartz. I would hope that this week they can sell more worldwide then at launch because they did it last week....and the week before...see where i'm going with this.
The idea of a second launch doesn't make sense by definition. A launch requires that the item cannot be purchased at all beforehand. Since over 600,000 people managed to obtain one before this new "launch" just last week I don't think we could call this a launch.
