Nintendo's surprise announcement of the upcoming 3DS handheld gaming system sparked a lot of discussion online yesterday, and some of that discussion happens on this week's episode of Power Button.  Join Joey Davidson, Brad Hilderbrand, and I as we kick around the mysterious 3D visuals that the 3DS promises, how news of a new system impacts the imminent release of the Nintendo DSi XL, what sort of games we expect to see, how the competition could react to the news, which crystals and prisms are needed to produce the next generation graphics, how the Virtual Boy fits into all of this, and why Joey enjoys Pokémon so much.  It's an hour of conversation and debate bookended by music from Nintendo's last stab at a portable 3D system.  Download this week's episode directly from PTB, listen with the player below, or subscribe via iTunes, and be sure to catch up on past episodes if you're joining us late.
