Merb and Rails did merge, but that doesn't mean any reasonably sized Merb codebases had any hope to migrate. It's a different framework with a different ORM. All those developers that followed Katz early on got burned when he joined Rails core. I do believe Rails.app will be released and Katz has recently given an update (it's dated January 27) but the first dozen comments at http://www.kickstarter.com/projects/1397300529/railsapp/comments http://www.kickstarter.com/projects/1397300529/railsapp/comm... will show that there has been some community concern that they bought into vaporware/Ember.js. Those comments went on from November 15 to January 25 before a Hacker News post solicited a comment. In regards to SproutCore, I was referring to SproutCore 2.0 which became Amber which became Ember.js. Ember.js seems to be coming together nicely, but we are already supporting 4 completely incompatible versions of it. Admittedly we are still at ember-1.0.0-pre.2 and I'm sure the APIs will eventually solidify, but it feels like even new patch versions have been radically incompatible. Definitely excited to see Rails 4, Ember 1.0, etc. for the record. I just have spent a significant amount of time cleaning up the messes of abandoned Merb codebases so I couldn't help but point out that Katz's legacy has been, at best, mixed here.
