After the disappointment that TGS was, regarding the "certain" announcement of a new Resident Evil installment, this came out of the nowhere.
I quote a part of the article from Eurogamer
What appears to be a Dead Space 3 logo and concept art have popped up in a video tour of EA's Redwood offices shown on Israeli TV.
The clip, hosted over on IGN, was shown on a news show called The Headlines. There's a brief glimpse of a logo board and a few pieces of necromorph art on a monitor.
When asked for comment, EA responded with "We don't have any news about the Dead Space franchise at this time."
Here is the original source. Just leave the player to load, you don't have to click on anything. There are only some ads that cannot be skipped. From around 6:00 to 8:00, they are interviewing people from Visceral.
The logo appears at exactly 6:08 and the concept arts follow shortly after.
If this was shown on April 1st I may had my doubts on whether what's depicted in the footage is real or not, but I am almost certain it is real. Most likely done on purpose, an unofficial "teaser" if you want.
So there you have it. Dead Space 3 is on it's way. Start getting happy, but not too much, as it probably won't come out for at least one to two more years.
