I can confirm that it is indeed legit, I decrypted it using the key and it does have data, we can't READ it for now, but yes, it is legit. For example I found a bunch of strings for the update section http://pastebin.com/3dni1xRF and the start of the junk data I found was "FST", like here http://pastebin.com/wktNfsAU so yes, you can start the hyping properly now. Haven't looked through all of it, but that should be proof enough for now.
