Ability to read wet fingerprints would be a nice feature to have ( part of my job involves cleaning things, so my hands are often wet and confuse my fingerprint scanner) but no cause for a new phone.
What would tempt me is if Google update ARCore to take advantage of multiple cameras / ir grid projectors ( a la Project Tango) to generate accurate point clouds ( 3D scans) of rooms and objects.
