They can get to the final and we're already seeing signs of One Direction-type bias from producers to get them there.
Having said that, the pleading for votes has bordered on the desperate and that, in spite of perfectly good performances, is generally a sure sign that the votes are not great for them.
Bottom line: they're a group and a group will not win this competition.
I think they'll probably limp into the final, with heavy support from producers and after being saved in at least one sing off.
I have a sneaky feeling they may hit the bottom two this weekend.
