I was just coming to tell you the same.
The choice was between 318, because most of the fleet at the moment consists of 319/320/321, or Embraer 170/190.
As it happens, Finnair chose the Embraer because it weighs less (smaller landing fees) and apparently is more fuel efficient than the bus. And Enbraers are used mainly on shorter routes with less people traveling, so all in all the managers decided it was a much more economical choice.
