So from various "in the know" media types, it looks like we're going to see:
1. Marler/Corbs (flip a coin - though Marler slightly ahead)
2. Hartley
3. Wilson(/Cole if not fit)
4. Kruis
5. Attwood
6. Haskell
7. Robshaw
8. Binny
9. Wigglesworth
10. Ford
11. May
12. 36
13. Joseph
14. Nowell/Watson (flip a coin)
15. Brown
16. Youngs
17. Corbs/Youngs
18. Cole/Brookes
19. Kitchener
20. Easter
21. Care/Youngs (Flip a coin)
22. Cipriani
23. Watson/Nowell
Only surprise is Wiggy being touted as first choice 9. It makes sense as he's in the best form/most consistent of the 9s named, and this close to a world cup age doesn't mean anything as long as they're still able to do a job in 7months time.
