Milestone denies Sega Japan's statement on future Dreamcast games
(Exclusive DCS news)
Since a couple of days a disscussion in our forums burns about Sega Japans statement about Under Defeat, which will be the last Dreamcast game, according to their product page on Sega.co.jp.
As you can see they have included the line "ドリームキャストの最後を飾るのは、このソフトだ!" which means something like "This will become the last Dreamcast game!".
We contacted Milestone Inc., the creators of some of the latest Dreamcast games, Chaos Field in 2004 and Radilgy in February 2006, and asked them about their point of view.
Their official statement was that they don't think that Under Defeat will be the last Dreamcast game and already got in contact with Sega Japan to secure that Dreamcast games and GD-ROMs can still be produced in future.
Again, the fate of the Dreamcast's future ended in a positive way and refuses to die once more. Eight years and running.
