Monk is my favourite class that I never play.
I typically play fighter, or ranger, sometimes thief, rarely wizard, occasionally cleric. More often then wizard, but not as often as rogue.
If I get the opportunity to play, I want to be awesome, super powered amazingness. I don't have time to fuck around with 'character development' or morales and other pieces of RP gameplay that I adore. It's all about the viscera when I get my moment on the players side.
With the latest Unearthed Arcana a new opportunity for role play ridiculousness rears, and I'm excited to see them in play.
I am curious to see how these classes will ultimately be introduced and I'm hoping that they'll do the handbooks like we saw back in the day.
The faux leather covered books with 'gold' writing? Fantastic stuff. The material lends itself well enough, but that would be a harder sell I suppose, then a 'sub class book' that addressed a range of options.
Of course, I doubt these, or any subclasses to be released to market, would be released stand alone, the book would be all of fifty pages cover to cover.
I expect they may do as they did for fourth edition and release 'manual of war' or some shit, which has options for martial classes, then the 'book of magic' and then the ... something.. can't call it bible cause folks'd shit themselves...
Anyhow... cool options, and the cantrips in starter spells were cool too.
