As well as the opening date, there's the question of what it will cost to bubble across the water. Dave Hill has blogged this for The Guardian ...
Note these words ... "in February Boris Watch reported indications that we might be looking at anywhere between £1.50 and £3 per journey." Good to know that the speculation is closer to bus-sports than winter-sports. But then the lift is being incorporated into the tube map (albeit with quite a walk from the nearest stations. The station on the south bank of the Thames is about 400m from the O2 dome and North Greenwich station).
The Nevis Range gondola is £11.25 return (but they have mountain+sea views!).
The only other comparable system in the UK (I think) is at Alton Towers - the Skyride, built by Poma ...
