It's pretty well known that QF wont have the A330's for domestic long term.You also have to wonder what type of next gen recliner QF may possibly install which potentially will make the new VA seats look second rate in J.
They aren't going to install flatbed seating into their new domestic airbus fleet.
Hard product wise for the bulk standard domestic Australian runs, I don't think you are going to see much. QF, VA and ZL won't put in the capital expenditure. Especially, whilst VA sticks with a B737 fleet.
