I think these figures are pretty reliable:
Boeing 787-8
6 firm orders starting in the second half of 2012.
Boeing 787-9
18 firm orders starting in the second half of 2014.
Options for a further 18 Boeing 787 of either or both variants, to be decided closer to the time.
Airbus A380
12 firm orders starting sometime in the first half of 2013, plus options for a further 7 A380.
Boeing 777-300ER
6 firm orders, with 2 already having arrived in the UK since October (?). One already in service witha second being fitted with its cabin interior in Cardiff. Options for 4 more.
Boeing 777-200ER
BA took delivery of 4 new aircraft within the last year or so, to add to the 42 777-200 that were already in the fleet.
Airbus (shorthaul variants)
I think there continues to be a steady trickle of new A320 types, replacing much older airframes, but I don't know the details.
I'm sure the Mods will find somewhere to place your thread, as this isn't really the spot for it.
