[quote name='javeryh']yeah, I'm holding out for a DS adapter to Revolution to play some of these games. If the controller does in fact have a touch screen it would make a lot of sense...[/QUOTE]
Nintendo stated last year that neither the Revo console or the controller would have a touchscreen.
Q: Will Revolution feature screens on the console or the controller?
Fact: No. At a June 2004 analyst briefing in Japan, Nintendo president Satoru Iwata said, "We have no intention of making a two screen console akin to the [Nintendo] DS."
If you think about it, a touchscreen controller which emulates buttons, analog sticks, etc, would be horrible to play with. Without any tactile response to pushing buttons, how would you know you had pressed it, or how hard you had pressed it? It just doesn't make sense. Using a touchscreen for analog control is one thing, but using it for button input would be a bitch.
For example, I have a Radio Shack universal remote which uses a customizable touchscreen. It turns out that it is a pain in the ass to use b/c I have to constantly look down at it to make sure I am pressing the right "button" on the screen. I ended up resorting to using the tactile channel up/down buttons more often than the touchscreen because of this. The remote is now in a closet somewhere.
