I hate to say this but this is NOT an attractive style when compared to the current body style. Those tiny windows in the upper deck is just way too low and it does not give you the open feel like the current Gemini 2. The angular shape seems weird and ugly, not as smooth and streamline like the current ones. It looks like Transformer has morphed into a double decker bus.
But don't forget that the Streetdeck is one of the lightest double decker currently in service in the UK at the moment. From what I recall, the unladen weight is about 800kg lighter than the "classic" UK-spec E400. Making allowance for some strengthening work to fit the bigger, heavier and more powerful engine, I think it is likely that this will come out lighter than the 2-axle double deckers in service in HK at the moment.
