In 1.19 you will be able to select from two preset keyboard layouts instead of just the original default. Layout B uses the arrow keys for camera control and maps a lot of the other buttons to do what XI's did. I believe you can still remap some keys if you have different preferences. But Layout B appears to move critical buttons (e.g. Arrow Keys, which were unbindable) to more XI-like positions.

Go to the "System" section and it's about half way through it under a series of icons for the classes.
