The airlift study did look at the entire continum (did I spell that right? - don't think so). I doubt you will see the A400 as suggested.
The A400 has come a long way since the airlift study was done (as part of White Paper?).
AFHQ is keeping a very close eye on A400M, especially as Army is going up in scale and weight on all of its vehicle projects. There is thought that it would make an ideal C-130J replacement in the mid 2020s, unless Lockmart progresses its 'wider gauge' C-130 concept.
Look for the C-130Hs to be extended to 2016 too as an SRP initiative... ALSPO and the contractors have already set the wheels (props?) in motion, pending Govt giving the OK.
As for the comment somewhere above that the only thing the RAAF will get to replace the Hercs in another Herc...don't be too sure. There is still a lot of dissatisfaction with the J, particularly with the engines and with the OEM's level of support. They don't make 'em like they used to...
