I understand the differences between 24f and 24p and I am not concerned in the least that the 24f will fit the bill for shooting in HD, but I am just feverously curious how well in SD the 24f will be.

All things considered shouldn't the new canon's resolve more detail in SD than the DVX with native Progressive?

This is just speculative but how does the XL2 compare to the XL-H1 in SD progressive shooting? Is it noticably better or too similiar to call?
 
A single field of 1080i (1440x540) will resolve way more for SD than a DVX could.

It's oversampled for the SD frame size, so with good software or hardware downconversion you will have superior results from HDV. (heck, just take an HD frame in QT and resize to 854x480 widescreen SD and have a look)

Shooting to DV the XL-H1 is slightly sharper, but the XL2 and XL-H1 are fairly close. The H1 is better in lowlight however. It's when you take HDV and downconvert to a better SD codec that you can easily see the difference the XL-H1 (and now the XH cams) makes.
 
Half sizing is the deinterlacing method best used when down sampling. It squezes the field together untill it's a solid frame.

And 720 definitely isn't 1440. ;)

Seriously, the point was more from an NTSC perspective--in that at a base level, a single field is much more than the SD frame.

Proper downconversion doesn't necessarily simply take one field and cram it into an SD frame. There's even more to be had if the conversion is done well.
