According to Boeing the 7E7 offers three versions with ranges from 3,500nm with 289 pax, 8,300nm with 217 pax and 8,300nm with 257 pax. If history is any guide, the longer range variants will comprehensively outsell both the shorter range variant and the competitor's shorter ranged alternatives - think 763ER vs 763, A310-300, A300-600R etc. If Airbus are to stand a chance of competing with the 7E7 they'll have to match its range and economy with, maybe, a separate, lighter, variant for short- haul ops. I would have thought this a bit of a tall order through just tweaking the A332.
