I can't believe there isn't a topic for this yet... I've been interested in this game ever since I heard that they were trying to go in a different direction for the DS version. To me this indicated a genuine interest in the DS and dedication on the part of the development team to make this game stand out. The GBA incarnations were always of the highest quality, so I had no reason to expect less from the DS incarnation. The new art style, smooth frame rate and full 3-D engine had me pretty much sold, and then they came along and threw in Wi-Fi support to absolutely seal the deal.
In my eyes the online features of this game may easily top Mario Kart. Customizable boards, uploadable replays, "skate crews", custom icons, and perhaps the coolest feature of all downloadable content such as new level objectives and missions that Vicarious Visions claims will be released regularly and free of charge. All of this in addition to standard 2 player online competition and an already lush variety of options in the offline game (skate park editor on a handheld? Sweet...). Looks like a great game and it definately deserves to get more hype around here.
