2017 - Nothing is known at this time, nothing known to be added in 2015 or 2016.
???? - New Coaster - Rumor - (2/18/17) A quick update on that S&S animated video. The video has since been taken down due to a copyright claim from S&S who also contacted Screamscape about the matter. According to the statement from S&S CEO, Tim Timco, the video posted were showing off a "high-capacity El Loco coaster and other ride concepts that were prepared as part of a sales presentation for specific potential customers." As such, they were not intended for public release and have now been removed from YouTube. So all links to the videos have now been removed.
But as we all know... the cat is out of the bag, and the concepts shown and described are certainly unique and interesting to be sure, and tell us a lot about what the future direction of S&S-Sansei coasters projects may look like. Now we just have to wait and see if Linnanmaki opts to buy it for a future season. If the park closes down the Vonkaputous liquid coaster ride that currently sits on the site shown, we'll know something new and possibly similar to this could be on the way.
(2/16/17) Is Linnanmaki in Finland planning on adding a new unique coaster from S&S - Sansei in the next year or two? I'm told that an animated video showing off a new custom layout coaster leaked out on YouTube briefly and was taken down, but looks like it was captures and re-uploaded again. It shows the new S&S creation appearing to be on the site of the park's Vonkaputous (Premier Rides Water Coaster) and features a drop out of the station down the hillside into a structure that will feature a drop/bounce elevator style track room, and then roll out into another section of track to encounter a rotating swtich track that will place the car onto the launch track, where it will launch forwards, backwards and then forwards again at full speed and into the rest of the layout and a return to the station. You can check it out below... but the question is, is this something the park is working on, or just a proposal to the park from S&S? (Video Removed)
