The leaked specs (if true) confirm lots of the rumors we saw over the last few months.
The specs say the Xbox360 will have support for 4 wireless controllers and the console will have 3 USB2.0 ports. The DVD drive will be a 'simple' DVD9-drive, with support for these formats: DVD-video, DVD-Rom, DVD-R/RW, CD-DA, CD-Rom, CD-R, CD-RW, WMA CD, MP3 cd, JPEG photo CD.
The detachable 20GB HDD will be included by default from the information we received (atleast in the 'full' package). We also got some sources telling us the Xbox360 will come with Wi-Fi 802.11 A, B and G support.
The Xbox 360 face plates will be customizable to change the appearance.
All games will have full support for the 16:9 format , 720p and 1080i HDTV (Max resolution: 1920x1080) and anti-aliasing.
Xbox360's IBM CPU will have 3 symmetrical cores running at 3.2 GHz each with 1 MB L2 cache. Each core has 2 hardware threads and one VMX-128 vector unit. Enough to boost an impressive 9 billion dots per second.
The ATI GPU will run at 500MHz with 10 MB embedded DRAM (256 GB/s memory bandwidth) and contain 48 parallel floating-point shader pipelines.
System memory will probably be 512MB of GDDR3 RAM (at 700 Mhz) with 22.4 GB/s memory interface bus bandwidth and 21.6GB/s frontside bus bandwidth.
The Xbox360 will also have a mulitchannel surround output.
