Despite all the talk around player changes and everything I think we have to be a little more reasonable.
This is the side that will be fielded come the first ball of the Ashes:
1. Watson
2. Katich
3. Ponting
4. Clarke
5. Hussey
6. North
7. Haddin
8. Johnson
9. Hauritz
10. Hilfenhaus
11. Bollinger
The only exception will be either Hauritz, Hilfenhaus or Bollinger moving aside if they wish to play Siddle, which may or may not be likely dependant on how he performs up until then, and indeed how the others currently in the team perform as well.
Hussey just failed badly in his two innings for WA. He could be on the way out. After North's ton, he'll probably keep his spot, but I can definitely see Hussey going. Judging by selector's comments and recent tour selections, you'd think one of Ferguson, Khawaja and Smith will get his spot.
