Well, it wasn't hard for people to make assumptions, one of the most interesting questions in the survey was the last one.
"What rules system would you use for psionics" And went to mention Level-based, feat and skill bases and "something completely different."
.... Lord knows why they put up such a question AFTER the PsiHB was out. One would assume such questions should be asked BEFORE even starting the book.
I think it was a reliable source that said more than 4,000 people repsonded to the survey in less than two days. Pity the public never got to hear the results.
