I still dont get what your talking about, but AAC is an Advanced Audio Compression file which makes files smaller than MP3 files and is a lossless technology. It, along with MP4 are used in Itunes music service.
Many divx and Xvid compressed video files use AAC for their audio compression. Its been around for a couple years I think.
as far as software to great games.... I dont get your question.
as far as new stuff, UDI, Unified Display Interface is supposed to overtake the current DVI (digital video interface) in a few years, Blu-Ray is making its entrance.... AMD is realeasing socket AM2, well thsy just did. Intel is launching the Conroe, theres always something. Verizon (an ISP) is pushing Fiber Optic internet service.. Vista is closer to release........
