DH, i been sayin they were gimicky from the start. i can almost garentee you this will be nintendos only handheld with a double screen and touch screen, IMO it just wont pan out that well.
thats not saying the system it self wont be good cuz it will be, i just dont think thoes features are going to make much an impack at all. (touch screen will be good for messaging tho, just no so much for most games.)
And for some good DS vids, try
www.gametrailers.com (my fav gaming vid website) they had 3 on there last week. they might be the commercials tho. but maybe they have more.
