I am not authorized to discuss the features of the program until the product launch at 11 AM April 12, 2010.
Hum, I guess the "newness" of being granted early access to software gets some people a bit over excited...
I suspect (but don't know for a fact) that you got added as a late beta tester via the NAPP call for beta testers? If so, you were chosen more for your test platform that your personal value as a tester...
Since Andrew and I are not part of any late beta program, I suspect that our reaction to somebody announcing that they are a beta tester and are being encouraged to state that they are a beta tester and then show images supposedly done in a beta Photoshop CS5 and then state they can't talk about how they did the images and what features they used is, well, silly.
The before/after could have been done with ANY version of Photoshop from the last decade...and the fact that you did it easier using Content Aware Fill (and maybe other techniques) is, well, I suppose YOU can't talk about it
but John Nack has already posted a blog post about Content Aware Fill that well, means you CAN talk about it (if you understand your NDA).
Since you are "not authorized to discuss the features" of CS5, you might want to spend your time actually testing the beta and filing bug reports–which is the general role of a beta tester ya know?
