They haven't even caught up to the pressures generated by early-90's unit injection systems. Thats why VW went with unit injectors (pumpe duse) in the previous generation of TDI. The primary reason for common rail today is unit injectors can't have multiple injection events beyond the compression/power strokes. Which is why manufacturers that have stayed with unit injectors, like Cat, use a "7th injector" post-turbo to produce the heat needed for DPF regeneration.
