Actually, the gifted kids CAN be accommodated with different learning styles in a University setting. There are honors studies, individual studies and opportunities to test out of but still get credit for classes that are too easy for them. They have opportunities and levels of study offered that they've never had before.
As for keeping gifted kids in regular and inclusion classes, it's not always a good thing. My son was teased and bullied because, despite being younger than his classmates, they "didn't understand what he was talking about". In one class a teacher told us that he had an incredibly advanced sense of humor and the teachers thought he was hilarious but his classmates rarely understood his jokes.
