You don't need a third turbo to eliminate lag, you can do that by using modern engine software programming and a different throttle response curve. There is only the risk that many people can't handle the sensitive throttle response and when too much boost builds up...
Right now, every new technology involving additional parts and innovative features is developed to meet new environmental restrictions and emissions laws in the near future. You might not be aware of it but in Europe, starting with 01. September 2009, only new cars with Euro 5 emissions are allowed to be certified in Europe. Starting with 01. September 2014, only new cars with Euro 6 emissions standards are allowed to be certified. Right now, there aren't many Diesel engines meeting Euro 5 and as far as I know, there is none on the market yet to meet Euro 6.
I'm also pretty sure that US states like California have similar, if not more restrictive emissions laws.
The tri-turbo is supposed to have lower emissions at same or even higher power/torque output levels. IF it also provides a better throttle response and less lag, well...the better.
