The new pricing was over 6 months ago now, so more related to 11 than 12. Strange choice of features to call out, when you don't include export to Vantage (long requested way to make Corona scenes compatible with GPU rendering), multiple LightMixes (long requested feature), cloud Density which is much bigger than lower horizon angles (but hey that is still useful as one of the smaller improvements, but I sure wouldn't call it out as the reason for 12 like you are doing), enhanced conversions well that is also long requested and again is not given as a main reason for this update, you miss out the super flexible new abilities in Scatter too... a bit of a cherry picked choice to try and make 12 sound small ;)
We never tried to minimize people's expectations for releases, except in terms of the Vantage export where we wanted people to be aware in advance that it would not include animating from your DCC in this version. That was an important expectation to manage.
All said and done though, let us know via the Feature Requests what features would make it a "big" update for you, as hearing that is the important part and we consider all requests there! Thanks!
