I'm not sure what the fields vs frames 'proof' adds to the argument
without taking into account the relative refresh rates of fields vs
frames also. Fields are irrelevant with progressive video as whole
frames are displayed.
1080p60 has twice as many pixels/s as 1080i60, as Jarod stated earlier:
1080i60 = (1920x540 pixels per field) x (60 interlaced fields per
second) = 62,208,000 pixels/second.
1080p60 = (1920x1080 pixels per frame) x (60 progressive frames per
second) = 124,416,000 pixels/second.
1080p30 will have the same datarate as 1080i60 however, and fast
action scenes may look smoother using the 1080i60 format.
