Just a few general points:
The graphics and text in that latest video are truly horrendous. Story isn't important, but theme and atmosphere is, so I hope the final product and later marketing material is much better. Thirteen was/is absolutely quality in theme and concept and without any story as such. The ride remains popular nearly 8 years later for a reason.
The ride will undoubtedly have a "world's first" marketing hook or unique selling point of some kind.
It is small, but it may still be thrilling. There looks to be some serious banking on it, which suggests speed. It's short length surprises me somewhat, because in the Smiler they said they were addressing the constant barrage of eventuate customer feedback saying that rides were too short.
It's significant because it's the first wooden ride Merlin have built, after years of resistance. If it is successful, and not rejected by the public as they always said one would be, it could be the gateway to bigger and better wooden rides. Imagine would could be done at Thorpe Park, or even Chessington.
