Oh hell no. I'm glad that Whatsapp is being mostly left alone, or at least that's what I see as a user. They ship some improvements and extraneous stuff (Whatsapp Status) from time to time, but the core of the app stays as it is.

Most people don't look forward to every time their app is redesigned starting from the icon up. It mostly doesn't get better, it gets worse to satisfy a Product Manager's CV checkbox.
