Same here - I never really liked the Nova ports anyway. They just don't quite feel right - they're close, but the difference is there.
There's the added problem that you can't play EV and EVO plugins on the Nova ports unless they've been specifically converted. This was less of a problem for EVO because the base scenario is so extensive anyway and the choice of truly good plugins is more limited. But I still wanted to play Frozen Heart, F-25, Beyond the Crescent, and several others.
For EV the situation is even more clear - once I'd played through the base scenario once it really does not hold my attention. The original EV's true feature lies in the huge number of downright awesome plugins available. Emulation is the only way in my opinion.
