I don't think Greece will choose "Miss Violence". It was not well liked here, it grossed only 15.000 tickets! even though it was released after it won 2 prizes in Venice. It also lost the Best Picture awards at the annual Greek Academy Awards, although it won Actor and Supporting Actress.Precious Doll wrote: Greece - Miss Violence - Well if Dogtooth can score a nomination then there is no reason that this insest drama can't make the cut as well.
My guess (and i am very confident about it) is that the film that is going to be submitted is "Mikra Anglia (Little England)" (http://www.imdb.com/title/tt3253650/combined). It was a box office champion (450.000 tickets) won 7 Greek Academy Awards (Picture, Cinematography, Editing, Art Direction, Costumes, Sound, Make up). A few days ago it also won 3 major awards (Picture, Director, Actress) in the Shanghai International Festival and it was announced that it has distirbution in UK and France.
