All those connections (composite, component, s-video and VGA) have one thing in common: they carry the video signal in an analog format. What about digital connections such DVI or HDMI? Will there be A/V packs with DVI and/or HDMI connections? If not, will you consider offering that in the future?
Todd Holmdahl: Xbox 360 will support HD component video output, which is compatible with nearly every HD-ready TV on the market today. Were poised to hit the sweet spot of the HD market at launch and as the market matures, and we will provide an HDMI for our customers when it makes sense. The reality is, you dont need HDMI for HD gaming.
In the specs, it is always mentioned 4X MSAA, but can developers choose a higher order anti-aliasing for their games?
Todd Holmdahl: The hardware supports up to 4X MSAA. However, developers can perform supersampling and hence render to a larger frame buffer as an alternative. This would be done in software. An important thing to understand is that most games end up turning anti-aliasing off due to the performance penalties from standard architectures. With Xbox 360 we designed the GPU from the ground up so that enabling anti-aliasing would not create any performance hit for developers.
