There isn't going to *be* a Zope3 to run on.

Zope2 is the only game in town, as far as appservers go.

Note that unless you scrap the entire model of a Plone site as an
application object hosted inside an appserver, you won't have a choice
except to run atop Zope2:  the Z3 appserver is going to be even more
moribund a year from now than it is today.

Z2 is at least *interesting* to work with at this point;  making the Z3
appserver WSGI'fied will be hard and pointless by comparison.
