I'm not sure I understand this question. First of all, the new defaults are in Camera Raw. They are in the Camera Raw preferences. Yes, you can open these preferences from Bridge (or from Photoshop) too, but they are the Camera Raw preferences and can be opened from Camera Raw itself. I'm also not sure why you posted this in Photoshop Mobile. Photoshop Mobile does not support raw files (yet).
I really really really hate not being able to set ACR Raw Defaults for different ISOs with one click. I shoot events on auto ISO and having set defaults for all the different ISO settings it made my life really easy!
