"The word of the DLC's name and content originally leaked on Xbox Live's marketplace"

"We're happy to confirm that Mass Effect 3: From Ashes DLC will be available at launch for all platforms. For those of you who have purchased the N7 Collector's Edition (including the PC Digital Deluxe Edition), you will get this content at no extra charge. We'll have a lot more details for you later this week! Stay Tuned!"

Tell me, where did BioWare confirm it was the Prothean?

And, as is stated in that article, it was leaked. The wiki will not accept this information because, while the name of the DLC has been officially announced, the only reason we know about the content is because of a leak.

I believe it is true, as does everybody else here, but that doesn't mean that it will be come later this week. As I said, their announcement of it curiously fell at the same time as the leak of it on XBL. This could be them trolling us, and we'll get something completely different with it. But, the point is, as I have been saying, we just don't know.
