Nintendo was speaking to investors today. Now they allow uploading games on SD cards. Finally.
They also revealed the new Zelda game.
The Legend of Zelda: Spirit Tracks DS
Link has the ability to control/create enemies and make them fight enemies. Railroad mechanic is an extension of Phantom Hourglass boat system -- riding a rail and shooting cannons. Very Phantom Hourglass like, but hopefully with new and fresh ideas. The new weapons and skills look like a good start, but Link looks kind of odd in his little conductor's outfit.
New Zelda looks better than my description probably makes it sound. Looks like a fairly traditional Zelda portable game, with puzzle dungeons and Phantom Hourglass-style touch mechanics. The train basically works like the boat in PH, running along the overworld (presumably on a rail defined by players). Enemy control mechanics look pretty nice -- link distracted a big Zora with a controlled shadow guard, then snuck around to hit it from behind.
NINTENDO, YOU GUYS ARE TROLLS! I LOVE YOU!
