I was googling around for this a few weeks ago. There's already a TV goggle thing which is battery powered and displays HDMI output, I can't remember the darned name though. But yeah, that'd put liveview straight to your eyes (via a lead though through which the HDMI is channeled). Not terribly inpressive resolution if I recall.
Touchscreen is only a matter of time. Of course manufacturers will do it because it frees up space on the body and means they'll need to deal with less mechanical buttons and bits to engineer into the body.
