787-10 is the replacement for A333. BR will not be ordering A330-900 Neo.
A321 Neo --> A321
787-9 --> A332
787-10 --> A333
A350-1000 --> 777-300ER
BR is ordering just enough A350 now to replace the oldest 77W. Logically, they would top this up when the newer 77W are ready for replacement... unless Boeing makes BR an offer it cannot refuse. BR will continue to operate 77W for a long time... they will probably convert some to cargo to compliment its 77F fleet so Boeing has a way back in if they really want the business. This is basically a huge blunder by Boeing. One of its best 77W operator and launch customer just ordered the A350-1000... The continue delay on the 777-9 is dooming its sales prospect. Someone better wake the F up at the Boeing HQ and get the engineering programs back on track.
