There's the 'approach' and the implementation. The approach is fairly 
clear: a focus on baby steps to integrate into Zope 2.7. The aim is to 
introduce as much as possible as make sense of Zope 3 facilities into 
Zope 2.

The implementation is still flux. Though that said, things like 
interfaces and adapters should be stable enough (as long as Zope 3 is 
stable in that regard), as there's really no difference between the way 
Five does them and the way Zope 3 does them.

For views, we're moving along nicely following the Zope 3 pattern. At 
the post-Europython sprint Stuart Bishop and I, with help from Jim, came 
up with a way to integrate them the right way for Zope 2 objects. I'm 
now pretty happy with them, though some more possibilities and details 
are bound to change still.

You can now even add views to existing Zope 2 objects, without the 
/edit/ hack, from ZCML. That this happens by way of "Structured 
Monkeypatching" shouldn't concern anybody. ;)

While Five is in flux, I expect the main changes you'll have to make in 
your applications is slightly altering some ZCML statements and possibly 
changing an import here and there. It also depends on who contributes 
what, as always. :)
