Hopefully. We've actually seen some (mostly superficial) activity in Sails recently, which is surprising and encouraging.

Trails is actually much more modular than Sails. The goal is the same -- to make your life easier -- and the conventions are rails-like (indeed, compatible wiyh Sails) but the technical design is completely different and actually quite a bit more "node-like".

Keep in mind that Trails is not a fork, but a Sails-compatible re-write. So there's no upstream code-level reconciliation that can happen, but I'm sure both projects can coexist and compete in the framework market on their merits.
