The scope of the game has a major issue with a rather epic story-line (Illithid! Gith! Dragon! The Underdark, and more, oh my!), if they only stick to Player's Handbook content, so I'm hoping they'll at least consider adding a bit more. Honestly developing a character is pretty boring but that's more a flaw of the D&D system locking you into your class-path by level 2 or 3, so there's really not much room for customization after that. That works a lot better in pen & paper where you have dynamic roleplaying and a responsive DM to fall back on.
