We asked, and now we know the specifications of Hacha's ultrathin PC20 PMP, as well as its slightly larger PA20 cousin. The third inch thick PC20 features a 3.0-inch QVGA screen, comes in 1, 4, and 8 GB flavors, and supports a list of audio and video formats including AVI Xvid, FLV, WMA, and MP3. It'll also play games, record audio, and playback FM radio. The PA20 has a 3.2-inch screen, measures just under half an inch thick, and comes with all the PC20's features bar the video games. Unfortunately, there's still no shipping or pricing information as yet.
