I think that the competition between the smartphones companies against each other threaten the manufacturers of cameras to bankruptcy.
Many companies can vanish but in my opinion with the exception of Nikon, Canon and Samsung.

Eastman Kodak Company, commonly known as Kodak, is an American technology company focused on imaging solutions and services for businesses. The company is headquartered in Rochester, New York, United States and incorporated in New Jersey. It was founded by George Eastman in 1888. From wikipedia

IDC Said:

Only companies that possess strong brands have the ability to be able to continue the competition, and only companies Canon, Nikon and Sony owns these specifications

Finally this still just a point of view, any thing, please put a comment.
