Remember the bulk of Pyramid is repoze.bfg - which is 1.5+ years old and has 100% test coverage.

Pylons really hadn't had anything other than bugfixes in quite some time, and had some problems with stacked object proxies which would have required a fairly substantial rewrite. Whether you consider Pylons dead or just simply finished is a matter of semantics. I still think Pylons is an extremely capable platform and I don't think you should be afraid to touch it. There is still plenty of mindshare around for Pylons.
