Perhaps the users that you categorize as "normal everyday user" will not (initially) notice much of a change. However most normal everyday users have the capacity to learn, and as their eyes/brain use newer more competent image capture they will learn.The numbers presented at the reveal will make everything seem as if it’s better, but like others have said, the periscope lens will be where it’s at.
The normal everyday user isn’t gonna notice much of a change. Except for the storage it’ll take for filming 8k vids.
Those users that already posses eyes/brain image expertise will notice right away.
