Highly unlikely. It seems that most super-GMs start to decline around 40. Vishy is 44. There have been some that have stayed quite strong into their later years - Korchnoi, quite a strong player at his peak (Peaked at 2695 @ age 48, quite late in and of itself), played for the world championship in 1978 and 81 (age 47 and 50), and stayed a regular on the tournament circuit - he beat a 2700+ ranked GM in a 2011 at the age of 80, and continued to to play seriously until he had a stroke late last year.
