So, it looks like they changed their mind about it being just character gen initially.
I've been a bit remiss in communicating this. Mike Mearls has said multiple times over the last few weeks that Basic D&D will debut on July 3rd (at the same time Wizards Play Network store get the Starter Set). That debut only includes character creation. A whole bunch more will be added to it on August 19th, when the Player's Handbook is released. It will then continue to be updated as the rest of the release schedule rolls out.Or maybe not. From the 6/30 Legends & Lore post by Mike Mearls
It’s hard to believe that we’re on the eve of the release of the first D&D fifth edition product. The Starter Set will be available at Wizards Play Network stores this week, starting on July 3. That day will also see the release of the basic rules for D&D on the Dungeons & Dragons web site.
For the D&D basic rules, our initial release will include character creation. It features the human, elf, dwarf, and halfling for races, along with the cleric, fighter, rogue, and wizard classes, all from 1st level to 20th level. As the Monster Manual and Dungeon Master’s Guide near completion, we’ll add to the basic rules with more material to grow it into a complete game. Our goal is to continue to make updates to the basic rules for D&D until the end of the year, at which point it will be feature complete.
