After a bit of research into detailed protocols, I'm going to shuffle my predictions (i.e. moving Emily from 6th to in front of Rachael and Ashley, and adding Alissa and Bebe).
And just for fun, I'll also put some numbers on my predictions (SP/LP):

1. Caroline Zhang (62/122)
2. Kimmie Meissner (63/115)
3. Mirai Nagasu (59/110)
4. Emily Hughes (59/106)
5. Rachael Flatt (53/109)
6. Ashley Wagner (52/108)
7. Alissa Ciszny (60/99)
8. Bebe Liang (61/96)
In other words, I think the veteran seniors will dominate the short, where the youngsters will have lower PCS and none other than Caroline have had their 3-3 ratified in the SP. If Rachael finally lands a clean 3-3 in the SP (she's had many 3/3's ratified in her LP's), then she could gain about 4 points and move ahead of Emily. The lack of clean jumps among the veterans (aside from Kimmie) in the LP means that not even the PCS can save them.
I expect Kimmie to lead after the short, followed by Caroline, followed by Bebe (who always does well in the SP at National's), then Alissa (who skated a great SP at NHK). I expect Kimmie to storm back (from her GP season) and land all her triples (but not managing to fix the toe-axeling or under-rotation on the 3T as the back end of her combos). That means in the LP, she will trail Caroline, who should win even with the lower PCS'. With her solid 3-3 and high levels and GOES on the spins and spirals, I think Caroline has a 1-fall cushion over Kimmie without the 3-3 or 2-3. I think (and hope) that Mirai will have resolved her under-rotation problems in the second part of her LP, and achieve a personal best. I think Emily will continue to fall or under-rotate her 3Lz and 3F -- National's being right around final exams time at Harvard might make her skate even worse than my predictions. Rachael (slow) and Ashley (awkward transitions) both still garner low PCS and can have really off days with their spins. They're both great jumpers, but both have had trouble having their 3-3 ratified in the SP. But I do expect both of them to wow the crowd with their excellent jumps in the LP and achieve PB's.
So the podium will be Caroline, Kimmie, Mirai, and the Worlds team will be Kimmie, Emily, and Ashley (though it's a close one between her and Alissa, it all depends on Alissa's nerves).
Now let's see how wrong I turn out to be!

(I reserve the right to change my predictions as National's draws closer.)
