"CV1 is completely different from DK2 (two sceens, different resolution, distortion, lenses, tracking system)"
That CV1 is completely different to DK2 seems to defeat the most of the point of it.
"While the games built with SDK 1.0 will work with DK2"
More importantly, will games built with SDK 0.8 work with CV1 (and SDK 1.0)? Without knowing what differences SDK 1.0 needs, developers are stuck in limbo.
