It's only been a few hours since Nintendo announced that the DSi would be coming to the U.S. on April 5, but gaming mega-retailer GameStop is already prepared to take your reserve money for the new handheld. Starting tomorrow, you will be able to reserve the DSi at GameStop, with a $25 deposit being required (this, of course, goes toward the full cost of $169.99).

If I remember anything from my GameStop days, it's that most stores have a set number of reserves they can take on systems--oh, and that Nintendo products sell like freakin' hotcakes. If you're serious about getting a DSi in April, you should probably head on over to your local GameStop tomorrow with 25 bucks in hand.
