yes, Kathy mentioned it in the "standards" thread at "the other BBS". She and hubby are going to be taking photos at the next few shows they go to (I think - go check her post if you want to be certain) to try to get more graphic material for the release.
I don't think she specified how far along they are in the documentary revisions, or publishing details.
If you are holding off buying tCSM because of the new version, I wouldn't hold your breathe. I'm sure they'll get it out eventually but if you don't have tCSM you should have it today. The new version won't have any groundbreaking new info on husbandry - most the new info will relate to the current understand of the corns genes, I think.
