Markus,

I don't see any reason why you could not have given more info.
You know that people were on the tip of their chair to hear about your development.

Your message made me think of the guy at the meeting at my old company who was always saying "give me 2 more weeks".
Two weeks later, same line ...

It does not have to be like this.
Some people here have a real bag of QTL.

The smallest effort of public relations would value YOUR product a lot.

my 2 cents.
