Terragen 2 jitters

I'm looking at the preview pics of Terragen 2 again...available at www.planetside.co.uk/gallery/f…

A few more days before the preview is released, and I'm already starting to get a little nervous about the new program...for a few reasons.
At first glance, the images look good, but given a closer look...and the actual quality is lacking in more than a few examples (realizing that these are just examples).
...like...in one image, the waves look amazing, but the fluffy clouds look grainy and almost look like a separate, lower quality render.
This is just one example of a very early preview image of what Terragen 2 will be capable of, but I have to assume that to get the amazing waves -and good clouds, render times will now run into several days...
No price has been mentioned yet because it's still too early, ...but I already know that I can't afford it if it's much past the $100.00 range.
Only being able to go by what I see so far, this thing is looking more and more like Vue...and alot less like Terragen.
To some (most maybe)..that may be a good thing.

Just some thoughts before the preview is released.
It will probably be alright.
