Apparently, this version has added two leader counters, Rommel and Montgomery, although their use remains unexplained. They may just be alternate counters for the DAK Headquarter and 8th Army Headquarter counters.
Someone who can read and understand the Japanese language rules might be able to clarify.
Presumably, this edition includes a paper map, while the earlier boxed editions all had mounted maps.
By all accounts, these are the only differences in this edition.
