As mentioned in another thread, the DSi is out. I maybe kinda bought one by accident. It's pretty neat. Haven't played much except for WarioWare Snapped! and Art Style Aquia which I bought with my free 1,000 Nintendo Points (formerly Wii Points). For free, I have no complaints. For $5 each, I'd still get them, if only to try something new. I don't think either is worth more than that, though.
Retail North America (Tuesday, April 7) - Gravity - Hannah Montana: The Movie - Rhythm Heaven (came out on Sunday; seems pretty fun)
Retail Europe (Friday, April 10) - Away: Shuffle Dungeon - Diva Girls: Diva Dancers - Jewel Quest: Solitaire - Love Is In Bloom: The Flower Shop Garden - Mind Your Language Series (Learn Japanese / Spanish) - Ultimate Band
Nintendo Channel Demos (out now; free) - Gardening Mama - MLB 2K0 Fantasy All-Stars - MySims Party
This is taken from this months EGM: I am not about to retype the whole story, so I'll recap it. Apparantly a group of people have developed software for your PC that will allow you to play GC games online.
