I would definately be more interested in DVCPRO HD format than HDV, no question there for me.

Hope 1280x720p60 becomes the standard now with 1920x1080p down the road.
I hope all interlaced video beyond 720x480i and it's PAL equivalent, does not catch on.

Nice hope, but highly, almost impossibly likely for the next 15 years, until the next pass at bandwidth allocation happens.
I realize you like P, but the fact remains that 1920 x 1080i has a much sharper detail. No, it doesn't do stills for freeze frame in football as well, but that remains a smaller segment of the viewing market. Further, for bandwidth purposes and acquisition purposes, it's a much more affordable proposition. 1080p is the grail, but that's a lot of money tied up in the changeover that's not going to amortize anytime soon.

Yes I do favor progressive video. 1080i is interlaced and some other things regarding interlaced video that I don't like:

With progressive video it is not just the better stills captured from video with motion. Interlaced video prevents us from using fonts with thin lines or they will flicker. Normal video and scanned photos can have flickering on thin horizontal lines using interlaced video. Conversion of interlaced video to different formats is difficult and much worse than converting from progressive video. Vertical scrolling of text is greatly affected by interlaced video.

Imagine the creative use of ANY font in our productions using progressive video. Folks who adopt progressive video will be able to use any font they want to! Vertical scrolling of text will look terrific at any scroll rate.

Let's let interlaced video fade away and have a progressive future! (no pun intended)

Umm...you've not created titles in 1080i yet, I'm guessing. You can use very fine fonts.
that said, while the rest of your post is quite nice in theory, it will be only a theory for a very, very long time. The state of the state and currently designated industry standards do not include 1080p. So, we might as well start a discussion on how nice 4K x 3.2K images will be, even though there is no display, camera, or editing option for sub 1M to achieve it all.
Nothing wrong with fantasy, just realize that all the 1080p desire will be for a long time is just that: fantasy.
That said, WHEN you start to work with HDV, or HD, if you want to render non-standard 1080p delivery for DVD, then you'll be able to do so. In fact, you can do that now. The question is, do you have an Avelink or similar player that can pass the p-scan in HD?

At the moment, you are absolutely correct, and even side by side most folks won't know the difference. Because darn few plasma or LCD screens are a full-resolution monitor. Most are 1600 at best, and few of those around too. That will change with the new Samsungs coming off line shortly, but there are already a lot of images.
So, deliver in 720p. As someone who mostly does broadcast work, we're just going to have to disagree on the p vs i issue. Both have advantages, both have drawbacks. For MOST things, i is simply better at this time. That too, will change in the future. But for the moment, p all you want. It's there for you, might as well take advantage of it.
