The situation is rather complex. Let me give you a few reasons why the VP50 still makes sense even if you have a 1080p display which accepts 1080p:
(1) The Toshiba HD-DVD player only outputs 1080i. Every 1080p display can "deinterlace" that to 1080p, but most displays will not do a really good job with it. The VP50 should be able to give you a perfect 1080p signal for HD-DVD.
(2) The Samsung HD-DVD player outputs either 1080i or 1080p60. For 1080i see (1). When using 1080p60, you have the typical NTSC 3:2 motion judder. If your display is capabable to accept and natively display 1080p with 24Hz or 48Hz or 72Hz, then the VP50 can give you judder free playback.
(3) Movie broadcasting is done in 1080i. See (1).
(4) Sports broadcasting is done in 1080i. This is even more extreme than (1), because sports is recorded interlaced. Deinterlacing this in a good way is really difficult and the VP50 is almost guaranteed to do it better than any display out on the market.
(5) Of course SD is handled much better by the VP50 than by (almost?) any display.
(6) The VP50 can do gamma calibration etc, if you want to ISF calibrate your setup.
There are more benefits, but these are probably the most important. Whether this is worth 3k USD for you, is your personal decision, of course. It might depend on how good of a video processor your display has built in. The better the video processing in your display is, the less difference you'll see with the VP50.
One thing you should make sure is that your display supports 1:1 pixel mapping. That's important to get the best out of it. You can benefit from the VP50 without 1:1 pixel mapping, too, but you'd lose a bit of sharpness/detail this way.
