Q u o t e:
The headers on the e-mail that I received was legitimate (it was sent by Blizzard).
And that is a reputable and legit survey company.
That's not to say that somebody couldn't craft an e-mail pretending to be the same thing, but directing elsewhere, but if it goes where it claims to, it's legit.
I did fill out the survey myself (and got some neat glimpses as to possible future development) and at no point did it ask me for any personally-identifiable information. Not even my first name. Gender and such were also completely optional.
