Tomorrow (as of right now anyway) The Elder Scrolls Online: Tamriel Unlimited will kick off on consoles in a closed NDA free beta. This is the full, complete game, and not a watered down version for console users to test ahead of the June 9th launch. It's a limted invite only to those who signed up (you can still signup here).

The worldwide console launch of The Elder Scrolls Online: Tamriel Unlimited on June 9th, is just a little over six weeks away, and we have a lot planned leading up to then. Kicking off the pre-launch festivities, we're very excited to be starting the console beta tomorrow. This is a limited public beta—it will be our one beta before launch, and you must receive an invite to participate. Prepare to explore the vast expanses of Tamriel with your friends, game-subscription-free, for the first time on PS4™ and Xbox One!

This is a pretty big deal, considering just the amount of desire and longing many players have had for ESO to come to console and it's a huge step forward for MMOs who have been trying to get into the console market now for the longest time.

The game is huge, well over 50GB as stated below:

With the console beta just around the corner, we're sure everyone is interested to know the size of the game client in order to get your hard drives ready. ESOTU is an incredibly massive game, both in terms of sheer scope and the data required to bring you this truly enormous experience. At the moment, the client will exceed a 50GB Blu-ray disc which means there will also be a large day-one patch that is somewhere in the region of 15GB.

As mentioned by Wodge below, the PS4 beta will be 39GB. Rather huge!

Fans have been waiting a very long time for the console release, considering that the Elder Scrolls is usually enjoyed either on the PC or the console and there are two different userbases, those who like the PC for its modding ability, and those who play on console for the pure experience and the fun of relaxing on the sofa and exploring the large game world. I'm pretty sure neither has ever completed the main story of an Elder Scrolls game, but hey ESO is now subscription free meaning that no matter what you do in the game, you're not obligated to pay for anything once you've bought it.

If you're going to play on console, this is a game you'll probably want to snag a disc when it launches. It'll come to consoles on June 9th, 2015.
