That picture shows absolutely nothing.
It is taken from Thorpe's MTDP, which is used to give the local council a rough indication of where rides and coasters will go. Notice how the 2012 coaster's layout looks very unlike Swarm's layout.
From what I'm aware, all we know about the 2015 coaster is:
-Not to exceed 850m in length (as said in the MTDP).
-Only a small amount of supports that can go in the water (under 10 I think, again from the MTDP).
-Will most probably go on the island next to Swarm (Island A), but could possibly go on Island E (the one next to the bridge, which currently has a big advertising board saying about visiting the park's FB or Twitter pages).
-If it goes on Island A, as said, the most probably one, the ride will most probably extend onto Treasure Island, have bridges with Swarm island and Stealth (spelling the end of Octopus Garden), opens up room for more round rides and 'thematic experiences' (by comparison, the blown up fire engine adjacent to Depth Charge seems to be such an experience that was outlined the MTDP).
-I've heard that because Swarm didn't exceed 40m, despite being in the spot which outlined a coaster of 50m maximum in height, that the 2015 could go above 40m, but not go above 50m.
As you can see, there's not a lot to go on really. All of what we know comes from the MTDP, and all it tells us is not an awful lot really. In honesty, I doubt Thorpe have had any serious thoughts about what the coaster will be yet (maybe the odd idea thrown into the pile, but nothing major).
So, time will tell I guess...
