I really want to see a proper Monk class myself. Not a martial artist monk, just a good old-fashioned ascetic priest who has devoted himself to his faith...
Keep in mind, even in anime 95% or more of all people called monks are just that: people who go around as part of formal orders of monks, using prayers and sacred talismans to banish evil spirits, while on an implied path towards enlightenment/devotion to the divine through self-discipline. They will never use fancy martial arts moves. If you ask me, it is something that deserves its own class (separate from but similar to the Cleric, more focused on internal spiritual development and less on healing, or a divine Controller).
Bare-knuckled fighting should be an assumed part of all fighting classes, especially the Fighter.
Mystical, lightly armored warriors with agile skill should have a dedicated swordsage-like class.
Edit: Overall, I think the important thing is that the guy in the second image is very similar to the guy in the first image, other than the fact that he is holding a sword. If D&D assumes that the first guy is a monk, and the second guy is a multiclass monk/swordsage, then it would be a lot better.
