Battlefront has posted a preview of 'Great War', their upcoming World War I (1918) book.

As has probably been previously mentioned here, the book will build off of the earlier Wargames Illustrated pamphlet, and provide lists for German, British, French, and US forces. According to the very last line at the link, it will be released next month.
Also of note is this paragraph on Battlefront's front page, that's part of the lead-in to the link to the preview -
We are thrilled to see how the wargaming community have responded to the news of Team Yankee, based on Harold Coyle’s 1987 alternative history novel of the same name. But remember, there is still a lot of other stuff happening before Team Yankee appears in November.
The Berlin figures have been coming out slowly (only half of the German products have been released so far, and the second Soviet product went up on the front page today), so there's been some speculation that this would mean delays. And it appears that both Great War and Team Yankee have now been delayed one month. While Battlefront hasn't said anything about the Pacific release, I suspect it's safe to assume that the Pacific books have been delayed as well, and will appear at the earliest in January and February.
