I see it as unlikely there'll be real consolidation, ironically for a language with a "one obvious way to do it" philosophy there many different opinions about how a framework would work. That said there is progress on consolidating some of the infrastructure, e.g. discussions on a creating a unified request objects for frameworks, a GSOC by Armin Ronacher (author of Jinja and Flask) under the Django banner to create a unified template compiler framework for both to share, and a work-in-progress PEP by Laurens Van Houtven about unifying some APIs that asynchronous frameworks have and bringing some useful base classes into the stdlib.
