Firstly, 1280x1080 and 1920x1080 are both...1080! The 1080 refers to the vertical rez, so games that use 1280 ARE 1080p games. Also, film can always be 'ported' to 1080 blu-ray, film has a HIGHER REZ THAN 1080. Also also, Wipeout is 1080, with a variable horizontal rez all the way to 1920. In fact i've never noticed a change while playing it, maybe when you fire quakes? Here's a screen shot from within the game, check the pics properties, it's 1920x1080. (you can't see the whole pic in vzcharts, at least on my pc, open image to see the whole pic!) I also have StardustHD which is 1080. Killzone2 was supposed to have a 1080i option, but I believe they took it out at the last minute.

 

1080p is a well documented standard which refers to a resolution of 1920x1080 that is not interlaced ... There is a wide variety of resolutions that have a verticle resolution of 1080 but only 1920x1080 is refered to as 1080p.

Now, strictly speaking film doesn't have a "resolution" in the sense that a digital image has a resolution and there is heavy disagreement (even professionally) about how film and digital images are related in quality. When you start talking about older movies, especially older movies that were filmed on lower quality film or using a smaller film format (8mm for example), the graininess of the film actually starts becoming apparent as you put it onto DVD and can be quite overpowering at higher resolutions. Unlike digital formats though, film still captures smaller details even though it is grainy and with a lot of effort to re-master the images to remove negative artefacts and produce clean and clear images at high resolutions. The reason I bring this up is the example of older musical documentaries would mostly have been filmed on 8mm cameras using cheap film (because of how low budget they have been) and unless the band was The Beatles there really won't be much of a budget to re-master the movie ... Or, to put it more simply, there really is no benefit to having Blu-Ray for the vast majority of these movies.
