Amelia- One of the favourates her elimination caused an up roar

james- since frankie was garys act some may feel james should be the replacement

two shoes- fun act

jonjo- could get votes because of remembrance day

James will certainly inherit a good amount of Frankie's fanbase. He'll also steal some from Craig and Marcus.

You also missed out 2 Shoes because they are the only non-manufactured group left in the show but still doubt it.

By the looks of it, almost certainly Amelia will be back.

I think the OP meant from the 4 acts up for a comeback - not overall.
