They're production constrained. The backlog for A32x is like 10 year long. At some point, better a slightly inferior plane now (well, in the next few years) than in 20 years. I assume they don't increase production (or at least not enough to massively reduce this backlog) because they don't expect this to keep up, and it's a massive investment.
