AFP announced the launch of the future classification in 2012 of the wines from Saint Emilion. I learned that Qualisud is responsible for the organization of the tasting and Qualité France of the rest (tax issues, notoriety, etc.)
In particular they mentioned that 96 applications were filed, 28 as 1st Grand Cru Classé and 68 in Grand Cru category, compared with the current classification with 15 classified as 1st Grand Cru Classé and 61 as Cru Classé. You can see that there are no major surge of applicants and, for me, the increase in applications is simply following the natural evolution due to the progress made here, in Saint Emilion, in many properties, which were sleeping beauties.
In fact, why not consider the requests of chateaux which have invested or have been taken over by ambitious owner?!
