This is what I think the selectors will pick (right or wrong):
Hayden
Hopes
Ponting
Clarke
D Hussey/Macdonald/White/Katich (if so swap places with Hopes)
Hussey
Haddin
Clark (if fit)/Noffkeiffit/Siddle/Hilfenhaus/
Bracken
Hauritz
Tait
Have to say it looks a lot more dire without Hogg/McGrath/Gilchrist
Tait is a walk up start after the WC'07 and his recent domestic performance.
Hayden will be given a go to help transition the team (and after his ridiculously poor world cup)
Hauritz is a walk up start replacing Hogg - he's better suited to the ODI format anyway.
Hopes opens for QLD, has experience and provides an all-round option.
Ponting/Clarke/Hussey/Haddin/Bracken all pick themselves (well Haddin doesn't, but will be given some time to settle in the side).
The only parts of the team that IMO are contentious (in the selectors minds anyway) are the final batsman (MacDonald if they feel an allrounder is necessary, and one of D Hussey, White or Katich if a bat is required) and the final bowling spot (which should go to Noffkeiffit IMO).
I don't want to see Katich anywhere near the ODI side, I think he should focus purely on tests. Once the team is a bit settled in a year or so bring in Jaques/Marsh (depending on who the selectors think is in the long term interests of the team. Eventually, for the next world cup I imagine seeing a team structured around:
*opener*
Hopes
Ponting
Clarke
*middle order bat*
Hussey
Haddin/Ronchi
Noffkeiffit^
Tait
Hauritz
Johnson
^This pick is purely because I'm a QLDer and Noffkeiffit is awesome.
Bracken will likely be too old by the next WC, as will Hayden (obviously), Lee and Symonds while Ponting will be on his last legs. Hussey may be past it but I think that he'll get a run at least. Tait, if he stays fit and quick will be in that bowling lineup. Hauritz should be our ODI spinner still (unless another Warne comes along, which is unlikely). Hopes will probably be in the team, though it will be seen as his final WC chance. Clarke will probably take over as ODI captain after this campaign. Ronchi may be the ODI keeper by then.
The opener spot will probably be between Hughes, Jaques and Marsh, while (depending on form) Hopes may move to the middle order to make way for one of those three.
The middle order bat spot will likely be between Hopes, D Hussey and White (though I think honestly that the selectors will keep Hopes up the top and put white in as the final middle order bat). There are a few wildcards here such as Henriques (who would help remove the need for Hopes) and Pomersbach.
The final bowler spot(s) will probably be between Siddle, Hilfenhaus, Geeves and whoever else has made their case domestically by then. Perhaps even Bollinger, though I think he's probably a bit more suited to the longer form of the game (and will be older).
Certainly I can see some big pressure placed on some of the older players by then, particularly if we start losing ODI series'. It could even be that Ponting gets replaced as both skipper and a batsman by then (he will, after all, be 37), though I doubt that.
