I like the Holga concept, although I doubt it can be manufactured cheaply enough, being not a mass-market product.
What I really would like to see, is a micro four-third format camera with slim, simple, retro-style body equipped with built-in hi-res EVF and only essential controls through physical knobs (aperture, ISO, shutter speed, etc). No LCD, no menus, no face detection. In other words, take Panasonic GF1 or Olympus PEN E-P2 and strip them down to absolutely minimum.
