Some news here from the US Consulate General:
Now that you have read the above information, if you determine that you are eligible to register with ESTA and that you do not need a visa, please register at https://esta.cbp.dhs.gov/. This is a secure website. Please return to the site a day after you register, print out the approval notice, and staple it into your passport. It is valid for two years. If your registration is denied, you will need to apply for a visa to enter the United States.
