I'm going to say
too, although I'm not madly enthusiastic about Batchelor.
As Kare said, the teachings were adapted to (and in) each new culture they were carried to. Over time they diverged further, which is why we have so many schools - each of which is still "Buddhism" by its own account and by any reasonable outside assessment. Now - in the last fifty years anyway - the different schools have come into regular contact with each other after their long isolation and have to resolve some of the differences.
At the same time, the dhamma is finding ways to co-exist with a scientific worldview and is having to downplay (or even throw out) elements which are totally inconsistent with that worldview. (And not just the dhamma - the Christians have had exactly the same problem, and the Moslems are going to have it even worse as and when their cultures become truly modern.)
Batchelor's is just one of the more radical adaption attempts. Not the worst, not the best ... but at least it's an attempt.
