I had thought for the most part that the budget for the games was very reasonable, until this happened. The plan that VANOC brought to the table for venues was very cost effective, instead of build 32 different venues, I think they built one permanent venue in Vancouver (the speed skating oval) and the ski jump out -- I think -- by Whistler, everything else was refurbished. The other part I liked about the bid was that it made some infrastructure upgrades actually happen, like the sea to sky highway (personally never driven it myself but I have friends that drive it several times a year) - my understanding was that was long over due.
What was the original budget $1.6 billion? compare it to other recent games past and future, that's a mere drop in the bucket.
The athletes village, I didn't realize they originally planned to spend $750 million on (a cost that has increased to $850 million), even if it wasn't supposed to be on the tax payers' tab and not part of their original budget with it being privately financed. With the company backing out this close to the games, at the end of the day there's got to be some sort of legal action they can take, even if for now they have to cover the cost.
But that's a hell of a kick in the nuts to the bottom line.
