I personally think many programs are now geared towards attracting an international crowd and aren't really rooted in any given country with regards to culture. To some extent, the cultural artifacts of such schools aren't country specific but rather focused on a set of skills and behavioral patterns.
For example, take a look at INSEAD’s accelerated 10-month MBA program. It's ranked the No. 1 MBA experience in the world, has about 50% of its classes going into top MBB consulting companies and is supposedly a French business school. Yet, you won’t find a dominant nationality at INSEAD, with Americans and Indians representing the highest proportion of the class at 9% each (and French and Chinese students each representing 7% of the class followed by Canadians at 6%) according to P&Q. With its cross-cultural vocation, INSEAD also requires students to be fluent in two languages upon entry and learn a third by graduation. And although it's a "French" school, classes are taught in English, which has replaced Mandarin as the top native language among students.
Since the goal of an MBA program is to provide new opportunities and career progression of some sort, I'm sure we'll see more and more schools evolve into a version of Insead, given their proven success.
