Veritas,

First of all, I have to admit, those Terragen2 renders are mouth-watering, indeed! Wow.

There are a few other issues to be concerned about.

1. The interface? As far as I can tell, Tbeta (1 is not yet released) is pretty hard to use.
2. The render times (OMG!) seem very long. I checked out 1 thread where a user was complaining about a rendering taking 25 hours and still only half way through.
3. The product shipping date for T2 is still unannounced and has been that way for many years. In fact some folks in the Terragen forum are starting to get a bit perturbed by it all.

Perhaps once a real shipping product is available,  it will be interesting to compare.
