I think "Xbox Next" (Much Better Name Than Xenon) will probably have this:
A Smaller Hard Drive, I Think M$ will realize that they did not have to put a 10GB Hard Drive in the Xbox, they will probably drop the size down to 4-6GB
DVD Drive that reads only Xbox Games and Music CD's, nothing else.
Same controller ports as the Xbox but you will be able to buy the second piece of the controller (The part that connects to the Xbox) as a USB port and it will include Drivers to install on your computer. (They Want to make that little more money
Same Cables as Xbox but you will be able to buy a M$ VGA port to play on your computer monitor (Again they want to make that extra money, and make it as much as a PC as possible)
Memory Card ports built on system
Perhaps a new color scheme, keep the dark black (Perhaps a Black and Red would look nice)
Thats what I think...
You guys are saying a bunch of crap like ya add this cause it will be easier to hack and mod. But M$ does not want you to mod so they will make it more diffulcult. Thats why I am being realistic with what I said above. Of Coarse I would like a 400GB Hard Drive, A DVD Drive that reads burnt games and everything you put in it, and all that that M$ would lose money on.
