There is actually to different pieces of news here. First you can now preorder the next installment of Mario Kart, on the Wii, at Gamestop.  Now for the 2nd and more interesting news.  The date that Gamestop has for the release of Mario Kart is April 2nd 2008.  As  you  know that a weird date for a place holder, also Gamestop must be pretty confident in the date to open the Preorders. I see two things wrong with this.  First Gamestop is batting about 50%, when the have a release date before anyone.  2nd this seems a little two close to Brawl for it to come out.  We will diffently be keeping an eye on this.
