Interestingly I logged out of my Google account in Chrome and immediately got an old style CAPTCHA. But not when I logged out in Safari (I very rarely use Safari). Edit- Nevermind, it looks like Safari left some google.com cookie lying around while Chrome deleted it. Deleting it gave me the old CAPTCHA.
