The 3DS eStore is going to start releasing new games on Thursdays. I think that starts next week (or whenever the next batch of games are coming out).
In the meantime, ten E3 trailers have been made available for free through the shop. You can see most or all of these online already (Joystiq had a bunch of them), but now you can watch these in 3D (if you have a 3DS, which you probably do not).
3DS E3 Trailers (Wednesday) - Animal Crossing - Kid Icarus: Uprising - Legend of Zelda: Ocarina of Time 3D - Luigi's Mansion 2 - Mario Kart - Metal Gear Solid: Snake Eater 3D - Paper Mario - Resident Evil: Revelations - Starfox 64 3D - Super Mario
Picked up some stuff in the eShop. QUICK REVIEWS: - Excitebike 3D: It's Excitebike, which is not a bad thing. It feels a bit slow to me. The 3D effect is pretty neat - when you adjust the slider, you don't just change the 3D, but it actually changes the camera angle, which is something I didn't know the system could do. That has potential in other, bigger games. - Pokédex 3D: Yeah, this offers nothing for me. Looks like a really good resource if you care about Pokémon. I don't, so it got promptly deleted. - Super Mario Land: It's weird to play this with a backlit screen and no motion blur. Much easier this way. You can play in black/white or the orignal light green/dark green. Much like with DS and DSiWare games, you can also choose to run Game Boy games in their original resolution for a sharper (but much tinier) image. I don't find the expanded image to be unattractive - it keeps the same ratio and is only slightly less sharp. - Plants vs. Zombies (DSiWare): Looks fine, plays fine, sounds fine, is the same as every other version. - Tetris Party Live (DSiWare): A cheap, very basic version of Tetris. Perfectly fine. I'd rather have the original Game Boy version.
IIRC, one of my friends got it used at an EB about a year ago and he still paid $49.95 for it. It's like Final Fantasy Tactics and Valkyrie Profile, a hard to find, and small printed, game that is very good.
