A trial will begin soon for the overhead lockers will be extended and be brought in line with those being delivered on the latest ones with the new BSI interior. http://www.ausbt.com.au/qantas-trial...-to-fit-more-bags-in-overhead-bins
The A330s (international and domestic) are rumoured to be receiving new seats in business but as the other thread on the topic indicates it is a contentious issue with no concrete announcement from QF
No rumours are currently circulating about the 737s. I would imagine in time we will see their IFE upgraded. I would hope for the same red leather seats as feature on the jet connect aircraft (don't know why the 767s weren't fitted in this leather colour it looks better then their black) with PTVs added for a uniform fleet. Still time will tell, perhaps we will see wifif and ipads.
