The BJCP guidelines have a long term ripple effect in the brewing world. The BJCP doesn't make the changes arbitrarily, either. I know they've had a goal of making minor changes or adding emerging styles more frequently, but an efficient, effective method for doing this hasn't emerged, yet.
Since having multiple versions of guidelines would impact brewers negatively, the BJCP has also limited the ability for people to reprint or embed them. They prefer that references be directly linked to the BJCP website.
The upcoming guidelines have taken a long time to assemble, review and revise. Still, once they're released, minor changes will happen for several months after the release as even more eyes look them over.
BeerSmith is one of the very few allowed to embed the guidelines. I know that adding them will happen, but probably once Brad is assured that typos, minor errors and revisions are complete. I expect that will be about 6 months after their release.
Enterprising users of BeerSmith probably have already started to compile the guidelines in BeerSmith's format. I would advise some caution if you choose to use those versions.
