And the only resolution advantages of the IIs over the other K-5 variants won't be noticeable except in those same circumstances. The IIs offers the potential for a small but significant gain in resolution, if the right lenses, camera settings, and shooting conditions are used, and if the result is viewed at relatively high magnification, whether print or screen. On the other hand it offers some (I don't know how much) increased potential for difficult to deal with moire when shooting and viewing particular subjects (e.g. fabrics) under similarly precise conditions. This will be a good tradeoff for some people and not for others. And for still others (probably most hobbyists) it doesn't really matter either way, because their technique rarely pushes the limits of the sensor. In which case one might as well buy the original K-5 (unless one needs the improved low-light AF performance of the II or IIs) or a K-30, and save money.
