1) 3.5million+ with tiny legs.
K2 was launched on a rather "small" PS3 userbase. As PS3 sales grow due to the slim and pricecut many will pick it up eventually thanks to it's reputation as the best looking game on a console.
2) Production costs of K2 vary from $30m - $60m depending on where you read it.
The anti-sony fraternity will always place that figure at the higher end.
As I don't know the costs for sure I will pass making a guess on this one.
3) Not before 2011/12.
