"Heard much from Yushchenko?"
Last i heard he was still trying to bolster his weak position by claiming he would not ratify the deal since it was a loss as opposed to Prime Minister Tymoshenko who claims it as a victory. Neither of them would accept the Ukraine is now solidly in the Russia orbit. Yushchenko's days look numbered with little chance of retaining his position in the coming election.

I hope the agreement holds for the ten years and I am glad to see the intermediaries have been sidelined, hopefully less corruption. My guess is that the Ukraine will still struggle to pay the market price in 2010 so let's see what happens then. If the Ukraine are being friendly towards Russia then they amy still get "mates rates" for some gas.

Now when will that northstream pipeline be online??

The northstream pipeline will not come online for at least 3 years.
The Finnish authorities have been dragging their feet because of the environmental impacts it will have.
The bottom of Gulf of Finland and the Baltic Sea are covered with all sorts of waste and it is feared that the building process will disturb it and affect the already fragile environment.
Also of concern are unexploded mines at the bottom of Gulf of Finland along the route.
