Engadget - Wherever there's a teaser video, full product info is sure to follow. Denon's decided to stop being so coy, and got its new SC2900 DJ media player fully out in the open. We pretty much got to see most of what's on offer, including that 7-inch non-motorized platter, and slew of format-playing options (mp3 / audio CD, USB drives, direct from laptop,) but we didn't know when, and how much. The answers to those questions? For Europeans, July, and €800 plus tax.
