The upconverting DVD players like Oppo do it at 1080p, and then only over HDMI -- and the results can be gorgeous.

They will also upconvert to 720p so upscaling players aren't a strong reason in my view.
There is one substantial reason, and a possible second reason to seriously consider 1080p if it's affordable.
The substantial reason is that it's the native resolution for the high def formats and a lot of hi def TV is broadcast. You aren't going to lose any resolution from the best current sources with a 1080 p projector but you will lose resolution with those sources by using a 720p projector.
The second reason is a maybe, it may or may not be an issue. You haven't mentioned your viewing distance but at close distances you will pick a visible difference in detail between 1080 and 720. At a slightly longer distance you won't. I forget the formula but it's certainly findable on the web. If your viewing distance allows you to see the difference, then 1080p is going to be a visually worthwhile improvement. At longer distances you won't see a difference unless there's some loss introduced by a poor quality rescaling of 1080 material to 720p.
Really, you can certainly argue that 720p is good enough if you're not sitting close enough to the screen to see the difference with 1080p but the 1080p machine is a little more 'future proof' and you may move to a different home and end up with a room in which you can see the difference and you will already have the projector.

Obviously an Oppo peculiarity. My Denon DVD player, the 2910, and the Pioneers I've owned have all offered upscaling to 720p as well as 1080i or p, and offer it with analog output as well.
Probably one of the ways that Oppo cuts costs and not a bad way to cut it in many cases.
I've got an LCD screen with 1366 x 768 resolution and find upscaling in players and receivers unneccesary. If I let the player or receiver upscale to 720p, the TV is going to rescale to 768 in order to display the picture so I end up with rescaling on an already rescaled image and that either looks no better or slightly worse than simply sending the standard def signal to the TV and relying on a single rescaling process.
In general I'm unconvinced about the inclusion of rescaling in players and receivers.

It probably depends on the respective qualities of the display and the player, and with a budget upscaling player I can well imagine that a display's upscaler would give better results.
My own Denon however upscales to 720p and 1080i, and when I leave it to output DVd at it's native resolution so the Panasonic PX60 does the scaling the results aren't anywhere near as good as when the player does the upscaling.

I found good upscaling players do a better jo than my Sony SXRD as well. I suspect this is an area were TV manufacturers cut corners.

As a general rule, upscaling isn't allowed via analog outs. While there are a few exceptions, here in the US it has to be done via digital connections. Its been decreed by the DVD Consortium. Perhaps things are different where you are, as in the case of region coding.

My 2910 only upscales on digital outputs.
