All Kindle books now have the EXTH 208 record (atv:kin1:base64:base64), regardless of platform (K1, K2/i/DX or K4PC). Again, the length of that record seems to be what determines the scheme -- the first base64 string is always a multiple of 16 bytes (the first 32 are always unique, the next 16 are always the same per book, and then the rest seem to vary between being the same per platform and unique) and the second base64 string is a unique 20 bytes. The books using the new scheme have a longer base64 string than the books using the original mobipocket scheme.
