After searching for the original source, we've found out that the Wing Gundam Snow White cover that we've posted yesterday was just a fanart by 7estige via pixiv.net.

Also, thanks to comment provided by Ramiro Armenta that provide us more construct proof that this is a fan art. 

Here's a tweet by AEMedia.org confirming that this is just a fanart! It was a hype last night eh? but we will sure see the true form of the Wing Gundam Snow White soon enough.
