I would say Caterham will do it this year,because they seem to be the only ones to climb and develop. I was surprised last year,when I saw their laptimes in certain races. They have the potential.
As for Marussia ,I’m sorry for glock ,as he’s carrer is on the Question if he stays there,because I don’t think they could score any time soon. Who knows maybe Marussia have some russian genious with them.
HRT- there’s no chance for them in the near future,if they don’t collect any major sponsors and then tehnical staff and designers,they will stay at the back forever. In case they manage to stay for two more seasons.
