Video from Press Event

Not great quality footage, but it shows some things extra compared to other footage.

Thanks go to @K_Toyama (Game Director for Gravity Daze) and @Shin_Ra

Another Video & Hands-on [UPDATE]

There's not too much new stuff here, but its another look at the first few minutes of the E3 demo:



Video streaming by UstreamThere's also another hands-on preview that I'd missed here: http://www.pspgweber.com/1010/gravity-daze-will-be-the-most-impressive-playstation-vita-game.html 

UPDATE: Seems I missed a few more hands-on impressions:

• Digital Chumps
• Shack News
• Sarcastic Gamer (This article also contains a short preview and video for Sound Shapes, which is worth a look if you haven't heard of it or seen it before).

Again, not a lot of new details, but it's good to see plenty of different news outlets reporting on the game.
 

Lovely High-res Concept Art

Flickr user "Shin-Ra PS3" has uploaded a bunch of HUGE versions of the concept art from the official Japanese site. The images are copyrighted, so I can't post them here but if you click the links below you can see them all (right-click the image and choose "Original" under "View all sizes" to get them in their full glory).

There are also a couple of smaller animated GIF images here and here, showing enemies.

Hands-On Articles (+video)

Some nice hands-on previews here:

• Gamespot
• Destructoid
• Siliconera

But first, watch this must see hands-on video at Kotaku (link), which contains the full E3 demo, including cutscenes (though text is hard to read) and combat, with a Sony rep explaining things.

Official Trailers
