I've played every single Kingdom Hearts game and had no problem getting used to any of them. Birth By Sleep has a really good story and I like the diversity and fighting styles of the characters, however I didn't like how they reused many of things over and over again. They even reused some of the same bosses (like Vanitas and Magic Mirror).
From what I've seen on the internet and Youtube, there are no reused boss battles what-so-ever in 3D. The boss do appear, but have different tactics and abilities. For example, the boss in the demo isn't the same when Riku fights him. This time he doesn't have any legs, floats, and uses magic.
