I also post on the forum that everyones talking about now, and I am very critical of sierra. As are most of the people there, for some simple reasons.
It took months for sierra to acknowledge Homeworld2's existance, by putting up a teaser page that counted down to E3, 2002. E3 came and went and HW2 wasnt there, nor was anything mentioned about the game until a lot of people got annoyed and a few fansites decided to boycott relic until we heard something.
Relic and sierra then managed to wake up and got involved in a pre-arranged irc chat, where we were told more about HW2. Two of the things stated by sierra were "HW2 would be a world-wide simultaneous ship" and "There will be a beta test open to the public"
Fast forward to June, where Marweas (alex rodburg) shows up, and mentions that HW2 will be out in europe about 4 weeks after the US release. Then, middle of august (2 weeks before the game goes gold) someone contacts the head of PR at vivendi games, and receives the information that "There will be no Beta, or Demo" Im sure Marweas knew those details, but he had decided not to tell us.
Sierra bring this shit upon themselves, and then have the audacity to whine about "A small and insignificant community" causing them too much hassle.
I feel sorry for Relic in all of this, as they have been unable to do much to assist the fans with regards to info about the game, even tho they would have loved too.
