There's been more competition in the regional market including clean sheet designs by new entrants, but they're all conventional tubes and wings and podded turbofans too. China's state funded A320/737 competitor is a clone with a shared engine platform too. Improving on current generation airliners is hard compared with improving what flew between 1920 and 1950, and consolidation happened because it wasn't profitable. Airlines and financiers don't like uncertainty either.
