Soul Link is in fact created by Navel who has indeed created Shuffle!. The setting is in space. And before anyone bashes the fact it's going to be some crappy-ass harem series in space, here's the plot I've gathered in AS forums. In space these group of space cadets are in a space station of which later got taken over by terrorists. Most of the plot deals with the teenaged cadets trying to reclaim their space station. From what I got in the AS forums, most of the endings in the PC game...
...will involve some main characters being killed off.
A splash page of the upcoming Soul Link anime series
can be found here. Now here are some really cool goodies. In here is a Flash page of
the Soul Link PC game (for anyone who knows Japanese). In here, you can download a rather trippy MAD OP of Soul Link
in this page; just click on the downloads under the heading "Soul Link".
