Well I can certainly see the possibilities in it....but is the stylus a Wacom powered type or is it just a pen point type device that just presses on the screen? Granted even if it was and had the resolution to support it...it could still be useful but only if there was some sort of pressure sensitivity even like that of the NDS.
Of course I would rather see a demo of a live and working product than a rendered movie...after all...they could make the stylus shoot fireballs in that demo if they wanted too.
Edit: Just finished typing and there's already another post. What a dream....hahaha....never know, maybe it was a glimpse into the future.
