Thank you for your answer. I hope it so as I plan to buy this component myself for my own projects.
But last time when I was using NGUI (it was latest at that moment 3.06.f6) and previous versions > 3.0.1,
it was necessary to fix several problems with Flash builds every update caused by some problems in Unity3d flash compiler.
It was not hard but it was annoying: yes, the root of problems could not be fixed in NGUI but workarounds could be done.
NGUI is fine system... And all is fine with Unity3d web player and other platforms...
But for most of my jobs Flash builds is necessary.
And I was scared that since 3.0 authors of NGUI ignores Flash platform as it is too rare and unpopular for Unity3d developers...
Unfortunately, most of web platform users still don't like to install any plugins except Flash.
I am glad that Flash is still supported
