Despite Gamestop's recent assurances that the Wii will be hard to find for at least six more months, some think that the system's sales figures are about to peak. Exhibit one: KBC Securities Japan, which recently downgraded Nintendo's stock from a "buy" to a "hold" recommendation because of worries that Wii and DS sales will slow after "explosive growth" in the last year.

The KBC report, which also includes a 30 percent cut in its 12-month price estimate for Nintendo stock, is also based on worries that the Japanese company will see its revenues continue to suffer as a result of the weakening American dollar. KBC's outlook stands in stark contrast to Nintendo's own bullish profit estimates over the last year of surging sales. Since everyone seems to be making predictions, we're going to go out on a limb and say that Nintendo's stock will plummet when contact with an alien race quickly erases all human want and destroys the international economic system as we know it. Hey, it could happen ...

For those of you who just can't wait until Sunday to get your hands on something Wii-branded, some North American Gamestop stores are already selling select Wii games that were shipped to stores on Tuesday. Our local store was selling Super Moneky Ball: Banana Blitz, Trauma Center: Second Opinion, Call of Duty 3, and GT Pro Series (other titles were in stock but explicitly embargoed until launch day). Of course, supplies and availability may vary at your local store, so call ahead first if you're planning on jumping the gun.

While you obviously won't be able to actually play the games until you have your hands on the system this weekend, you can stand them up next to your Wii accessories from Target and stare at them lovingly as you count down the seconds.
