You're correct on this.
From 960x1080 vs. 1280x720 both upscaled to 1920x1080 resolution is a major challenge to develop. It simply cost more money and time. You cannot take X0 720p game and do "simple" port to PS3. Future may not be like it was before, first made PS2 and then did Xbox release. Now it might go other way around for nextgen games and PS3 requires so much more work.
But you're not correct on this. It shouldn't take that much more time and effort if done right and even then it should be fine. From my experience, even with games that are cross platform between the 360 and PS3, it will be minor changes at best and minimal effort to have it done. Remember, even though 720p and 1080i/p are the same aspect ratio, 480i/p is not unless it's anamorphic. Even then developers have to keep that in mind when developing their code. They don't typically have a set of assets for 480 and then a set of assets for high def either. It's the same stuff and it is being scaled proportionally and displayed right. So simply taking the new res into consideration is trivial when they already have to worry about 480. Now supporting multiple resolutions to begin with, that was a pain to deal with when you were used to only dealing with one set resolution.
One explanation to provide horz-only "half scaler" in SDK is they give two-pass scaler rendering.
* pass 1: game renders background and scenegraph graphics, without overlay HUDs and texts. 960x1080 -> 1920x1080
* pass 2: game renders overlay HUDs and texts with pixel-perfect results to 1920x1080 buffer
-> buffer is drawn on screen
Not the case here.

"the choices of resolutions that a developer can use have been increased to be 960x1080, 1280x1080, 1440x1080 and 1600x1080......So this means that at the very least Sony could begin requiring that all 1280x720 games also support somethingX1080.
Possible, but hasn't happened yet.
But the main point is that by forcing the dev to not just develop for 1280x720, but to also force them to develop for somethingX1080 resolution, that will produce games that look great on 720p TVs and also look better on 1080p TVs than if devs only developed for 1280x720p and had PS3 scale that (both horizontally and vertically) to 1080p."
As I said before, it's trivial since it's already being done with 480.
