There is controller shaking. It's clever though me thinks. It's sort of a tug of war with the creatures souls, basically moving the controller up from resting position (to activate the accelerometer). It essentially replaced a button press in a reasonably elegant manner.
Just going off the visuals. Anything that does not have a separate battle screen now reminds me of FFXII.
As for shaking, let's say I don't share your optimism. If I wanted to go soul-fishing with accelerometers, I think I would prefer a Wiimote, however I only have Resistance to use as reference. At least with the Wiimote I am constantly reminded that if I try to scratch my ass while playing that I am going to lose this minigame. I am really hoping the Sixaxis motion sensing dies an early death.
Why am I homeless? Why do all you motherfuckers need homes is the real question. They called it The Prayer, its answer was law Mommy come back 'cause the water's all gone
