Uhh i think Krejza's sure to be in the touring party. Maybe they'll have McGain back by then though (bit of a forgotten man) or even at a long shot Warne. He's unlikely to start in England, but if the pitch looks like it'll turn i'd say Krejza's as good a shout as any.
Apart from the loss of Hayden, which i don't actually expect to happen, it's hard to see any big unforced batting changes to the Australia side before next summer. I don't think Watson will get another look in at batting 6 and he's not a frontline bowler, so Symonds should hold on to the loosely-used "all-rounder" position. Lee and Clark will not and should not be dropped, the selectors seem to like Johnson and he's come pretty good of late, Siddle is the man in possession of the fourth bowling spot and whether he still is next summer depends on his own performances. I'll go for, injuries permitting:
Hayden
Katich
Ponting
Hussey
Clarke
Symonds
Haddin
Johnson
Lee
Clark
Noffke or Tait, fitness depending- i don't think Siddle will be a big success, and i don't think Australia will want to bring in someone new to an away Ashes team. Or Krejza, if the first pitch looks like it'll turn, which it probably won't.
England will probably recall Vaughan when they realise how poor their batting is in India and the West Indies, mistakenly believing he'll make any difference. Collingwood will be the man to give way after continuing to not be very good. Sidebottom's broken, Pietersen loves Harmison and loves his five-man attack, Prior will put in a good show with the bat on Indian pitches and keep the gloves. I'll go:
Strauss
Cook
Vaughan
Pietersen (c)
Bell
Prior (wk)
Flintoff
Simon Jones if fit will get a recall, otherwise Broad will hang onto his place with no wickets and a pretty 40 not-out
Anderson
Harmison
Panesar
