Personally I am looking forward to the MM a lot. Having things presented in a better/more organised manner will really help with running things "on the fly"
It looks to be having the DCs for the save of magic that cratures will be using and hopefully the CRs will be more accurate.
ALl In all from what I have seen and reqad I am looking forward to the MM
The DMG seems like the least useful, but then in all the versions of the DMG I haven't seen much I really needed very often.
It has been helpful to some degree to settle questions about creature abilites and of course it has the entire magic item mail order catalog in it
But I seldom reference it in comparison to the amount of use my PHB and MM get when I am DMing.
