I don't believe it was the case that anyone was "shocked" about elliptic curve being broken by quantum computers; that was well understood long before NSA's Suite B announcement or Koblitz's paper.
Please read my edited comment again, people were shocked not by the fact of quantum attack of elliptic curve, but by
> The NSA seemed to be suggesting that practical quantum computers were coming so soon that people who had not yet upgraded from RSA to ECC should not bother to do so, and instead should save their money for the future upgrade to post-quantum protocols.
