My thinking is that the Apple apps will represent the "top tier" pricing, as they do in the desktop world. iWork on the desktop is 79$, pretty high up their compared to most indie apps. Also, I believe the iWork apps represent exactly this kind of "high value" application: the videos look pretty complex and flashy. Thus by selling the iPad version for less than half that, it is my belief that indie devs will take a cue to sell for lower.<p>This is of course simply speculation.
