Forgive me for continually posting random pictures, but here's an overlay of the two plans, which is probably the clearest look at how the development area has been extended:
Now, time for some speculation:
If this for a layout change, I have an idea for what it could be. And I don't expect it to be anything drastic.
Many people noted that the ride takes a lot of speed into the suspected splash zone area, and that that area could be quite trimmed. And even if not, it does have a lot of speed and doesn't do a lot.
I expect that the short layout is, in part, a creative choice. The ride very much looks designed to be big, fast-paced and hard hitting. Rather than creating a long, drawn out experience, it seems to be a "throw everything at you as quickly as possible" experience, designed so that when you hit the brakes, you're left stunned, and begging for more in a good way. You won't feel short changed, but you'll want to go round again.
So a potential adaptation to the layout would be as follows:
Now forgive the crude drawing, but let me explain what this would achieve:
-A straight section post-splashdown, to include one or two powerful airtime hills.
-A new turnaround, which could be dragged out for some sustained forces, or be quirky / different (like the other turnaround)
-Give more space pre-brake run for another airtime hill, rather than the airtime moment post-turnaround as currently suggested.
My particular thought on the final point is that they could create a 'double down' airtime moment which is similar to Loggers Leap's drop. This would be in the exact same position as Loggers drop, and serve as a reminder/Easter egg/reference/whatever you want to call it to the ride (something that Thorpe and John Burton, the likely Creative Lead of the project, love doing).
This would address the concern which a lot of people had about the ride's ending, whilst keeping in line with the (what I expect to be) feel of the ride. May not be everyone's cup of tea or what people want, but it's what I feel would be most likely. Equally, I think this is a sufficient change to improve the ride.
Obviously, this is all speculation. But I don't see anything more significant than this.
