Excuse my belated reply but I`ve just returned from a week away.
The books are in the final stages with the publisher and Im assured that it will be out in June.. hopefully within the next week. Prices are as stated above, with the US prices whatever the conversion rates are AFAIA.
Please be aware that the books are not a follow on from Ch'ang Hon TKD Hae Sul and they do not contain the same stuff (ie. boon hae) - vol 2 of that is still being worked on. They are a completely different set of books designed for learning or revising patterns and include the GTF patterns of GM park + the Silla Knife pattern all in step by step photographic form with the 'in-between' motions captured as well. They do have a complete (and honest) TKD history (vol 1) + kihaps points (for orgs that use them) + a history of the patterns and who, apart from Gen Choi helped make them & when etc + plus some other bits & pieces. I have tried not to repeat stuff, for example the in-depth research into the pattern meanings that can be found in CHTKDHS.. this type of stuff remains with that set.
The books can be brought seperatly or as part of a complete set at a reduced price - which I think should be available on release.
When I get a release date that can be more definitive.. I`ll post it.
Ps. The book titles are "The Encyclopedia of Taekwon-Do Patterns" (not "forms)
