I was playing around with these in GAME no less than an hour ago. At present on the test model the images pop out but they don't animate. You can change their poses so Samus is firing her cannon or in Morph Ball mode or whatever, but that's about it. Although i will say the Kirby 3D model is as cute as buttons
I'm assuming the system will be updated after launch with new firmware or something that makes these cards actually do something 'cause right now the novelty wears off after about 20 minutes. It has great potential for things like Pokemon (why no Pikachu card?) but right now it's just a gimmick. Give it time and we'll surely see it go somewhere. Hopefully. Unlike say, the six-axis controls on the PS3, which I've not seen used in a game since Uncharted 2...
Incidentally, if anyone's concerned about the 3D effects still, I did a little test today. I've had next to no sleep, so my vision was kinda wonky already this morning (not the best time to have to go to work). Figured now's the time to test the 3DS at its worst, right? Well, to be fair when I had the 3D on full it wasn't easy for my tired eyes to adjust, so adapting to it took a little longer than normal. It's usually damn near instant for my eyes to adjust but when I'm tired it takes a few extra seconds for them to focus on the 3D screen. But when I turned the 3D down to about 60% it was fine, worked quite nicely. So it's handy having different settings on the effects, it means you can find your own level depending on the state of your eyes at the time.
The battery life is still a minor concern, but it's only a huge drain when using the advanced features like the AR cards. Playing the games doesn't seem to be as draining, even with the 3D set to a decent level. The staff at GAME have been conducting constant tests on it (by which I mean you can't get Ayla off DOA) and they've found that the cameras and the AR cards are by far the most draining. With the 3D set to about 60% which is about right for most people's eyes, the battery lasts a little longer in their experience.
Funny how there's a big poster on the tills saying the test model is for staff use only, no customers are to use it in case of theft. Ayla's reading it out loud before she signs it and I'm 3 feet away from her messing about with the AR cards. I could abuse that trust SO bad if I ever went evil...
