I'm only relaying the information, I'm just a messenger. But ratings can't be given unless if the product is close to finish.

The Elder Scrolls Online got a PEGI rating of 12+ recently, and as you can probably guess, games get rated when they're complete. Since Zenimax finished development early, we might get an early release (doubt it though) since it shouldn't take over a year to fix bugs and glitches.
Also, check out the new website!
