I think you might have mixed things up, unless I got the wrong information aircraft due this year are:
A320:
A7-ADE, DF, DG and DH
A300F:
A7-AFB
A332:
A7-ACC (already here), CD and CH
ACJ
A7-CJA

"1x 319 (that came out of nowhere)"
This A319 which is a CJ by the way was mentioned all the way back in 2000 when the first A319CJ was ordered as it was an option which was only firmed up last January.
"Anyway the A300 is an old, inefficient aircraft and is not a long haul aircraft despite the routes that QR try to fly it on ie. KUL & CMN"
I agree on the CMN comment, the aircraft makes TECH stops in Tunis a lot but I have to disagree with you on another point, while the A300 might be inefficient when it comes to fuel burn it is important for QR in that it does much better than the A330 on the short Middle Eastern and South Asia routes. Unless they get more traffic rights the A320 is no replacement on short routes, why do you think Lufthansa are keeping theres and infact getting more. Another point is that the A300s are very cheap to lease or purchase which renders the fuel burn or maintanence costs irrelevant.
