I, too, will be interested to see if the new "newbie" books will be compatible with 4E, but I strongly suspect that they will be.
As for the Compendium, what exactly is "the rules" Races, classes, powers, feats, magic items, combat stuff skill challenges, etc etc etc?
Will it include stuff published only on DDI? Or only from the books? Both?
It could be very valuable or totally useless, and I am not sure yet
From Dungeons & Dragons Roleplaying Game Official Home Page - Product (Rules Compendium):
In addition to providing an overview of the game and how it’s played, this book presents the core rules in a format that is easily referenced during a game. It includes information on level advancement, combat, experience points, treasure, skills, equipment, and more.
So, basically most of the things outside of actual races, classes, paragon paths, epic destinies, feats, rituals, magic items, monsters, etc ... so basically everything in abstract, nothing specific.
[As a side note, FYI, the product catelogue Dungeons & Dragons Roleplaying Game Official Home Page - Product Catalog is updated with most if not all of the products mentioned, and has some clearer info than just bits and pieces that have been tweeted.]
