I think that in trying to build the "real" Deco + Dexterity + WSGI 
publisher + Chameleon + Skins deprecation as add-ons for Plone 4.0 
*now*, we'll end up driving features for Plone 4.1. That is, the work 
for Plone 5 probably starts in parallel with the work for Plone 4.1, 
i.e. very soon if not already.
