NCsoft has two highly anticipated sequels in the works: Guild Wars 2 and Lineage III. For both the release dates seem to be slipping a bit. Lineage III got off to a bad start at the end of 2007 when it was announced that the source code had been stolen by some of the programmers who had taken it with them to a Japanese competitor. A significant part of the development team had to be replaced, which may explain why it is slated for release in 2011. Guild Wars 2 was originally planned to be published before the 2009 winter holiday season. At the beginning of this year that schedule was revised to ‘2010/2011’. Seems we won’t have to be bored in 2011 at least.
Update on June 2012: Guild Wars 2 is still in beta, but supposedly will be released any moment now..
