The Magic Carpet loading system has been confirmed since last Feb. when this document appeared:
Also, in a recent travel podcast, the 'people mover' loading system was specifically mentioned.
You can listen to the full podcast, which is about 8 long minutes of vacation planning info before the Rockit part, here:

Points of interest:
- "People mover" loading system
(Magic Carpet) enabling a capacity of roughly 2000 people per hour.
- Track filled with 'sand' to reduce noise.
- Lots of music options, and it'll be actual current music, not custom tracks created specifically for the ride.
(And hopefully more than the 25 tracks mentioned here)
Besides that, the station has been far enough along for quite awhile now to tell it's not going to be dual load.
