User blog comment:Aleksandr the Great/Prothean Squadmate is Officially DLC/@comment-1655340-20120222172227/@comment-1655340-20120222174013

They confirmed it, they didn't confirmed that it was the Prothean squad member, That was said nowhere in the confirmation.

I believed from the beginning of reding this article that it was true, but it's a "leak". Notice how Lancer and Spart have said nothing in this blog? Usually one or both of them say at least something. But until BioWare confirms that "From Ashes" is the Prothean, it is a leak and rumor, even though we all know it's true.
