CheleK,
i understand your concern. and yes, that's one "weakness" (if we want to call it that) of Wilber's approach. however, he does try to summarize his work to make it appeal to more mainstream. "Integral Vision" is his latest attempt. check it out if you haven't read it yet. i think it's as simple as we can get without watering down Wilber's integral approach.
as for "Buddhist view of 21st century" that Hokai mentioned, IMHO, Shinzen Young is doing an awesome job of integrating the core of Buddhist technology. here's one example of how he's doing it:
see: 5 Ways to Know Yourself
ttp://www.shinzen.org/Retreat%20Reading/5%20Ways%20To%20Know%20Yourself.pdf
notice that each of the 5 ways represent a tradition within Buddhism (as well as other mystical traditions).
one thing i like about Shinzen's approach is that he is *secularizing* the dharma by making the vocabulary more palatable to different people from different religious background, and especially for the scientific community.
see: Getting the Lingo
http://www.shinzen.org/Retreat%20Reading/Getting%20the%20Lingo.pdf
from my point of view Wilber and Shinzen represent a complementary approach at integration. Wilber gives the *very* big picture, Shinzen integrates the technology for awakening.
that said, i guess it will depend on people's temperament. i like big pictures and i also like detailed and systematic approach. that's why i groove with both of them
