Any printed manuals would probably only be for a special collector's edition, or in physical console versions of the game, and even then, the player's handbook is over 300 large pages. Even if that was cut down to, let's say, 150 by not including anything past Level 10, and trimming out flavor and artwork I really can't see a physical manual that big.
I agree it would be a special edition thing only, but BG1&2 did it so it can be done. However, I do assume that no one will bother to actually make one. Those that have never played D&D will have to rely on in-game info to find the game character features, only with on-line FAQ's.
