Once developers get the hang of the coding and architecture, a choice few will release their engines to other developers (for a few of course) and this should help push the PS3 furthermore.
Killzone 2 seems like a demonstration of what the PS3 can achieve. Maybe the collaboration between Sony and Epic for Unreal Tournament will push a general release of their engine for other developers to use.
