Let me try to answer your questions with my current knowledge.
-Yes there will be a new engine, a updated version of what we have right now. Meaning a Graphics change, frame rate change, physics change, all that. Basically they'll try to update this engine and when they're done they'll add more features.
-Yes the Cyberix 3D Team confirmed that transferring your old projects to the new one will be possible.
-Not likely, they most likely won't change the site because we don't need a new site, it's pointless.
