Barring a freak of nature that results in a horrible performance, I can't see Alice or Jackie being shut out. I think Fighting Gravity (my picks behind Poppycock), and Michael and Ashleigh stand a good chance of making it through (if the judges don't chew them out and they give a performance like they did in a wildcard round). We've got enough singers, counting the two I mentioned above. I don't get the appeal of HasPop. Studio One Beast Society might make it. Murray is pitiful and hope he gets cut. I'm sure one remaining magician will get through to the finals.
So my picks would be Fighting Gravity, Alice, and Michael/Ashleigh. I think the first two and Jackie will make it, a magician for variety. Not sure on the rest.
And I don't like Debra, either. Or Nathianel Kenyon, but maybe he'll have the tweens voting for him. I'm on the other side of the fence with a lot of acts that are fan favorites (or not) this season.
