I reckon things are really changing in a whole lotta ways ......
MPL and CASR 103 are just a coupla parts of that change.
Old days - whatever you wanted to do (recreational/GA/CPL) you started with PPL and worked your way up the elevator, getting off at whatever floor took your fancy.
Now - if you want to fly recreation, and that's all - go RA. Pretty soon there'll be no real difference between the RA and PPL - RA's will be able to fly heavier and heavier craft and fly into CTA and all those other things. So, if that's your thing, that's where you go - but you'll be increasingly cut off from moving on to CPL/ATPL, because that will be a totally different stream.
If you want to spend your life as a professional pilot in GA - then you'll follow the current PPL/CPL path under CASA rules. And that'll be it - you'll have a shedload of fun and pick up great flying skills, but you won't fly big jets for a major airline - you makes yer choices.
And if you want to sit at a computer all day in a big jet, then you'll go MPL. And that'll be it - you'll miss all the fun, but you'll have a nice life with a (fairly) steady income.
