Who Will Be Playing???

We know that Lizzie will not be in the next life series, but will there be someone new replacing her?

I think either that or it will be knocked down to 16, and someone like Mumbo will not be playing. (mumbo normally has other commitments) or Ren.

I would love to see someone new, and potentially have a nice clean roster of 20 for a future life series after this one.
