Paizo seems to have shown at least a little bit of interest in this direction and I'm fairly happy about it. Not every monster needs to be completely statted out ala 4e, but as long as the option will exist and perhaps thematic abilities given as examples then I'll be happy.
If nothing else I import combat stuff from 4e all the time to spice up the monotomy that can be 3.P creature and encounter/combat design. Was one of those changes I genuinely loved from the system. Encounter design and monster creativity jumped up the roof and was very dynamic with the introduction of conditions such as bloodied but was also rather simple to set up while still generating fun results.
Though its a shame it took 3 MM printings to finally fix the math issue.
