Great news came from Bethesda as the developer announced that new set of beta invites were sent to selected group of registered email addresses.
The official The Elder Scrolls Online site said:
We’re greeting the new year with a round of beta invites. Check your registered email address to find out if you received one, and don’t forget to look in your spam folder just in case.
Even though release date is getting near it is also said that those unlucky ones still have the chance to get into beta before official launch of TESO.
