They all sound good but I'm curious to see wether anyone's got their mind set on one.

The Nextbox is the Next Xbox from Microsoft which is (apparently) coming this November. It will (apparently) come in three styles (Normal, HDD and windows) and has a superior Live network based on "Gamer Cards"

The PS3 will link up to the PSP for (apparently) movie-storage capabilites on UMD. Like Microsoft, they belive their machine will be a Media Center for the whole house to enjoy.

Nintendo haven't confirmed the control system for the Revolution. Expect "something that just hasn't been applied to games yet" With built-in Wi-Fi, router and DS linking capabilites, the emphasis is now on online gaming for Nintendo's machine.
