I think 720p will be a standard screen resolution for apps in the next year. It's a very common resolution outside of phones now and I think it will be the resolution of most high end phones in 2012.
The reason that qHD isn't really supported so far, as it's kind of a mash between WVGA and HD. Only a few devices supported it and it is a pretty awkward resolution.
