A few months ago, Ole Lange has started to monthly give us the news concerning NoLimits 2, and now for May, he has presented a few preliminary screenshots of terrain in NoLimits 2. See
http://www.nolimitscoaster.de/ and click News.
I must say, it looks pretty amazing! The water looks a bit weird to me still, but the terrain with the grass looks way better than what I am used to in NoLimits 1. I would say: take a look on his website.
