She was correct, because just a few hours later, OhSnap (Kara Kroupa, Marketing Coordinator at NetDevil) replied with a detailed explanation of what exactly happened. According to OhSnap, the video "showed up on youtube first because I asked the emissaries to spread it around before I made the video announcement. With all intention to explain the details here later." Unfortunately, Alpha had not read the information regarding the video when she first replied to the post, so she treated it as a breach of the NDA. Fortunately, there was no real issue, and no damage was done save to Alpha's keyboard, which now has OJ sprayed on it from her laughing at finding out the "leak" was intentional.
Now, after months of quiet, we have some Jumpgate Evolution footage! Take a look after the break at this "leaked" real footage of gameplay of the citadel.
