Honestly, I feel it's unrealistic, at least if you're speaking of the USNews rankings. If you're talking about Forbes, WSJ, or whatever else, then yeah it's definitely a possibility because those are all over the map. These kinds of articles/press releases come out all the time and every school is fighting to move up in the rankings.
For USNews, I don't see H/S/W moving out of the top 3. The competition to fill out the top 5 is stiff, and I don't think Chicago, Kellogg, or MIT are going anywhere either. MIT and Kellogg are both in the process of building brand new facilities, which are currently weak points in their respective programs. Chicago has seen a huge climb in the rankings and it continues to be a favorite school among many applicants.
I think Haas will stay in the top 10, but thinking that it has a shot of moving into the top 5, at least within the next decade, is unrealistic. Beyond the next decade - your guess is as good as mine.
Out of the top 10 programs, I would say that Haas, MIT, Columbia, and Tuck seem to have a little bit more self-selecting applicant pool. H/S/W and Chicago/Kellogg draw applications from people all over the map. There are a lot more people from the West Coast applying to H/W and Chicago/Kellogg than there are people from the East Coast applying to Haas.
