Alright, based on the news update thingy, mods won't be updated until a couple weeks in the future. As such, we're looking at release next weekend.
The release will include multiblock structures, introductions to all forms of portal travel, introduction to worldgen, common methods of gathering resources automatically, power generation systems, and some specific mod-based sections for Factorization, Railcraft, and Thermal Expansion. Gregtech is covered, and it is assumed that expensive recipes are left on. The tutorial will not cover anything, and with mods such as Railcraft, Twilight Forest, Steve's Carts, top-tier items and features are completely ignored. However, the content being taught would be enough to carry a survival playthrough for weeks, plenty of time for advanced tutorials, modpack updated tutorials, etc.
