I may be overly optimistic, but I truly believe that for those cases where 'sufficient' lack of movement works- 'pixel shift' or 'real resolution' may be one of the most significant technologies to hit the digital still market in recent years… likely even greater in magnitude to the removal of the bayer sensor AA filter.
As I understand, by capturing full color information at each pixel, the pixel level definition increases substantially.
See the link below. The text translation does not make much sense- but pay close attention to the subtitles to each individual image and note where the enlarged examples fall within the overall scene. Note the increase in micro-detail in the enlarged magnification areas.

LOL- definitely went a little overboard with my first paragraph in the above post.
But seriously, do check out the examples of the above link. Shows both some impressive increase in fine details at magnification and also shows some examples of the errors that 'can' occur with subject movement (see the enlargement of the ferris wheel). Interestingly, subject movement does not always result in artifacts (as demonstrated by the motorcyclist shown in one of the magnifications). Also note the response in the trees (can observe a large area with no adverse effects, and an area with movement artifacts).
