Oh, and as for the "bad developer record" card, http://en.wikipedia.org/wiki/High_Voltage_Software#Developed_games.
Those are the people who are making The Conduit. This is not their fourth game, it's like their 30th. They do not have a $70 million budget and 4 years of development time. They do not have Sony as a publisher.
Hell, if I was making a guess, ignoring the previews and reviews, I'd say The Conduit had a bigger chance of being mediocre than Killzone 2. Of course, it should be a very good game, and this is completely irrelevant to the topic, but I just thought it needed to be addressed.
And yes, the lack of advertising will hurt The Conduit.
