I don't think Rails-style MVC frameworks are going to disappear for a lot of content heavy internet sites, but API first architectures are going to continue to become popular I think. That is part of the reason I built radial https://github.com/RetroMocha/radial
The tooling around rapid API development seems very immature right now, but it's going to keep getting better. Once it is drop dead easy to write API's first, you will see a lot more apps having a HTML5 app, Android app, iOS app, Windows 8 app, Mac app, etc. as more of the standard and less of an edge case.
